Why OpenClaw Needs Reliable Network Routing
OpenClaw can connect to a model provider successfully and still feel unreliable. A model request may time out while the application is starting, fail during a streamed response, or appear to hang while the client downloads supporting resources. These symptoms are not always caused by the model itself. DNS resolution, an unstable proxy node, an incorrect API endpoint, or a process that does not inherit the desktop proxy settings can all interrupt the connection.
Clash helps by controlling how network traffic is routed. In rule mode, it can send selected destinations through a proxy while leaving other traffic on the normal network. That is usually a better starting point than sending every connection through a remote server. OpenClaw may contact several hosts, depending on the provider and enabled features: the model API, an authentication service, a package or resource host, and sometimes a service used for logs or updates. The exact hostnames are determined by your setup, so avoid assuming that one generic “AI” rule covers them all.
It is also important to separate three different layers. OpenClaw selects the provider, model, and API endpoint. Clash chooses a route for matching network connections. The provider’s own account and service determine whether the model request is authorized and available. A proxy can improve reachability, but it cannot repair an invalid API key, grant access to a model you have not been authorized to use, or correct an unsupported endpoint.
The Goal
Make OpenClaw’s required provider connections predictable, route only the destinations that need a proxy, and retain a simple way to verify or roll back each change.
Identify the Request Path Before Changing Rules
Start by recording the provider name, the configured base URL, and the model identifier shown in your OpenClaw configuration. Do not paste API keys into screenshots, support posts, shell history, or a shared configuration file. If you need to inspect configuration, redact credentials first. A provider may offer an OpenAI-compatible API, a native API, or a custom endpoint; these are not interchangeable merely because they use similar request formats.
Next, determine how OpenClaw is launched. A desktop app, a terminal command, a background service, a container, and a remote host may each use a different network environment. A system proxy toggle in Clash Verge does not guarantee that every command-line program or service will use it. The process may ignore system proxy settings, run under another account, or use its own DNS and networking stack. Confirm where OpenClaw runs before deciding whether system proxy mode, TUN mode, or explicit proxy variables are appropriate.
Keep the first test narrow: use one provider, one model, and one request that normally completes quickly. Note the time of the failure and the exact error text, but remove tokens and personal data. Compare the OpenClaw log with the Clash connection log around the same moment. If no matching connection appears in Clash, the request may not be passing through the route you expected. If a connection appears but fails, inspect its destination, selected policy, and node before changing DNS or adding more rules.
1Prepare Clash Verge and Choose a Routing Mode
Use a current Clash Verge or Clash Verge Rev installation with a compatible core such as Mihomo. Import and activate a configuration from a provider you trust, then verify that the client shows an active profile and at least one working proxy group. Test the selected node with a latency check, but treat that result as a basic reachability check rather than proof that the model API works. A node can respond to a test URL while a provider’s API remains unreachable or rejects the request.
For an initial diagnosis, use the least complicated mode that captures the OpenClaw process. If OpenClaw is a browser-based workflow and it follows the operating system’s proxy settings, system proxy mode may be sufficient. If it is a terminal process or a background service that ignores system settings, try explicit proxy variables where supported, or use TUN mode when you need Clash to capture system traffic more broadly. TUN mode may require administrator permission and can affect other applications, so enable it only when necessary and verify what it changes on your device.
Pro Tip: Change One Layer at a Time
Avoid enabling TUN mode, changing DNS, switching to Global mode, and editing provider settings all at once. If the connection starts working, you will not know which change fixed it; if another application breaks, you will not know what to undo.
Map the Provider’s Actual Hostnames
Use the base URL and the provider’s documentation to identify the API hostname. If OpenClaw reports a timeout while fetching model metadata or authenticating, inspect the relevant log entry for the destination host. Do not infer hostnames from a brand name alone: a provider may use separate API, login, telemetry, or content domains, and those may be hosted on different infrastructure. If a request is sent to a custom gateway, route that gateway’s host rather than a domain belonging to the model vendor.
In Clash Verge, open the connection or traffic view while reproducing one failing request. Find the connection that matches the time and destination in the application log. Check whether Clash sees the expected process and host, which rule matched, and which policy group or node handled it. When the connection is missing, first check the application’s proxy support and launch context. When the connection is visible but routed DIRECT, review the matching rules. When it is routed through a node but still fails, test a different authorized node and check the provider’s service status, endpoint, and credentials.
A rule should be as specific as practical. A provider-specific hostname is safer than a broad keyword rule such as ai, which could match unrelated sites. Domain suffix rules are useful when a provider documents several API subdomains under one domain, but do not add a suffix unless you have confirmed that the provider uses it. Rules are evaluated in order, so place a specific rule before a broad rule that could match the same destination. The examples below are templates, not a list of universal provider domains:
In many subscription configurations, the proxy policy is a named group rather than the literal PROXY. Use the policy name that exists in your active profile, or select the provider’s intended proxy group in the client. A rule pointing to a nonexistent group may not behave as expected. If your existing profile already has a suitable rule set, prefer a small local override or supported rule provider over editing a generated subscription that will be overwritten at the next update.
2Configure OpenClaw and Test Model Connectivity
With Clash routing prepared, verify OpenClaw’s provider settings independently. Confirm that the provider name, API base URL, model identifier, and authentication method match the provider’s current documentation. Check for accidental spaces, a missing path component in the base URL, a stale model name, or a key copied from a different account. Do not place a secret directly into a command that will be saved in shell history. Prefer OpenClaw’s documented secret store, a protected environment file, or an operating-system credential facility.
If OpenClaw documents support for standard proxy environment variables, you can test with a temporary environment for that process. Replace the port with the HTTP or mixed-port value actually shown in your Clash Verge settings. The following is a pattern only; variable behavior differs across operating systems and application runtimes:
Do not assume that a SOCKS port accepts an HTTP proxy URL, or that an HTTP port accepts a SOCKS URL. Check the port and protocol in Clash Verge before configuring the application. Also note that environment variables affect only processes launched with that environment; an already-running desktop application or service may need to be restarted. For a persistent service, follow its own configuration method rather than editing a global system file without understanding the impact.
Run a Layered Connectivity Test
Test from the same device and, where possible, the same environment that runs OpenClaw. First confirm that the local Clash core is running and that its proxy listener is available. Then test the provider’s documented health endpoint or a simple request with a valid, protected credential. A successful connection to a generic website proves only that the proxy can reach that website; it does not prove that the provider accepts your account or that OpenClaw is using the correct API path.
Use OpenClaw itself for the final test. Send a short prompt to the selected model and watch both the application log and Clash’s connection view. This can distinguish connection setup from response delivery: an immediate authentication error usually points to credentials or account permissions, while a connection timeout suggests routing, DNS, or upstream reachability. A request that begins and then stalls may indicate an unstable node, a streaming connection interrupted mid-response, or an application timeout that is too short for the model’s response time.
For command-line checks, follow the provider’s documented endpoint and authentication format. A generic request structure might resemble the example below, but the URL path, headers, payload, and model field must come from the provider documentation. Keep the key out of the literal command and avoid printing authorization headers in logs:
When using streamed output, do not judge the connection only by whether the first token arrives. Let a small request finish, then repeat it once after a brief pause. If short calls succeed but longer responses fail, check the node’s stability and the provider’s timeout or streaming requirements. Avoid repeatedly submitting large prompts during diagnosis: retries may create duplicate usage or charges, and a stalled client may still have an active request upstream.
| Observed symptom | Likely area to inspect | First useful check |
|---|---|---|
| OpenClaw cannot resolve the API host | DNS handling or hostname spelling | Confirm the configured base URL and compare DNS behavior with Clash enabled. |
| Connection timeout before a response | Route, node, firewall, or proxy inheritance | Check whether the request appears in Clash and which policy handled it. |
| HTTP authentication or permission error | Key, account, model access, or provider settings | Verify the key and model permissions without exposing the key in logs. |
| Response starts, then stops during streaming | Node stability, stream handling, or timeout limits | Try a short response and compare one alternate node. |
| OpenClaw works only in one launch method | Different process environment or service account | Compare proxy variables, permissions, and network mode for each launch method. |
3Refine the Rules and Troubleshoot Failures
Once a short model request succeeds, return to rule mode and make the routing policy as narrow as your setup allows. Route the confirmed API hostname through the chosen proxy group only when direct connectivity is unreliable or unavailable. Leave unrelated destinations on their existing routes unless testing shows they also need a proxy. This reduces the chance that local services, package downloads, or unrelated applications inherit an unnecessary remote path.
After each rule change, reload or update the active configuration using the method provided by your Clash client. Then repeat the same small OpenClaw request and check the connection log again. Confirm that the expected hostname matched the intended rule; do not rely only on a “connected” indicator in the application. If you use an automatic proxy group, check which node it selected and whether that node remained active for the whole request. A group that switches nodes during a long-lived connection can sometimes interrupt streaming.
Diagnose Common Failure Patterns
- Clash shows no matching connection: OpenClaw may bypass the operating system proxy, run in a container or remote environment, or have been started before proxy settings changed. Test with a supported per-process proxy setting or a carefully controlled TUN setup, then restart the application if needed.
- The connection is matched but goes DIRECT: Review rule order and the exact hostname shown in the connection log. Add only a confirmed, provider-specific rule and ensure its target policy exists in the active profile.
- The connection uses the proxy but DNS fails: Check that the hostname is spelled correctly and that the active profile’s DNS configuration is healthy. Do not replace the whole DNS configuration with a copied snippet without considering the profile’s existing fake-IP, IPv6, and resolver settings.
- Requests fail only on one node: Select another node from a trusted group and repeat the same small test. A low latency measurement does not guarantee that a node can reach every provider or maintain a long streaming response.
- The provider returns an error quickly: Read the HTTP status and provider message. A 401 or 403 commonly points to credentials, account, region, or model authorization rather than a route timeout; consult the provider’s own guidance before changing Clash rules.
- Only long or streamed responses fail: Check whether the provider supports streaming for the chosen model, whether the application timeout is appropriate, and whether the selected node is stable. Reduce the prompt and output length to isolate the issue before increasing timeouts.
Global mode can be useful as a short diagnostic: if a request works in Global mode but fails in Rule mode, that suggests the route or rule match deserves attention. It is not a recommended permanent fix by itself. Global routing can send traffic that should remain direct through a remote node, add latency, and make it harder to identify which destination actually required the proxy. After the comparison, return to rule mode and correct the specific match.
Protect Credentials and Respect Provider Rules
A proxy does not make an API key safe to share. Keep credentials private, rotate a key that may have been exposed, and follow the provider’s terms, regional requirements, and rate limits. Do not add broad rules or use another account to bypass access controls.
For a maintainable setup, keep a short record of the provider hostname, the rule you added, the proxy group used, and the test that confirmed it. If you maintain a local override, preserve a copy before editing and recheck it after subscription updates. When a provider changes its API host, update the narrow rule rather than broadening it to catch unrelated services. If the problem returns, compare the current request destination with your notes before replacing a working profile.
A reliable configuration is one you can explain and reverse. Start with one confirmed endpoint, route it through a stable policy, verify a complete request in OpenClaw, and then add other destinations only when logs show they are required. This approach makes model access easier to troubleshoot without turning every connection on the device into a proxy connection.
