OpenClaw Error Troubleshooting: Common API Error Codes and Solutions

Dealing with connection failures or request timeouts on OpenClaw? This guide covers common OpenClaw error codes and fixes to help you restore service fast. Whether it's an API return error or a client-side error, follow these steps to resolve it.

Authentication and Permission Errors

Error codes 401 or 403 usually indicate an invalid key or insufficient permissions. Start by checking that your API Key is copied correctly—make sure it includes the full characters and has no extra spaces. If the key is still within its validity period, try regenerating it in the OpenClaw dashboard and updating it in your configuration file.

Some users may see "Rate Limit Exceeded," which means you've surpassed the free tier request limit. The fix is to lower your call frequency or upgrade to a paid plan for higher quotas. Check your current usage via the official console and plan your request pacing accordingly.

Connection and Network Issues

Error codes 500 or 503 point to temporary server-side failures. Wait 5 minutes before retrying, and also check whether your local network can reach the OpenClaw website. If "Connection Timeout" happens often, try switching your DNS or using a proxy node.

For "SSL Handshake Failed" errors, update your system root certificates or disable firewall blocking. Windows users can run "certmgr.msc" to import the latest certificates, while Mac users can fix this through Keychain. Avoid modifying SSL verification rules arbitrarily to prevent lowering security.

Request Parameter and Data Format Problems

Error code 400 is often caused by incorrect request body formatting. Open the OpenClaw debug log and check if your JSON fields are missing quotes or contain illegal characters. It's recommended to use the example templates from the official SDK to avoid compatibility issues from manual coding.

If you see "Invalid endpoint," it means you're referencing a deprecated API path. Go to the OpenClaw documentation to get the latest endpoint URLs and replace the old ones in your code. Also, pay attention to the domain differences between test and production environments.

Account and Version Conflict Troubleshooting

If subscription users encounter "Account suspended," log into the dashboard to check for any unpaid invoices. Once the balance is cleared, the account usually recovers within 24 hours. Free-tier users who frequently switch devices may trigger risk control locks—submit a support ticket to verify your identity and unbind devices.

Some legacy users see "Unsupported API version"—check whether your client version is too old. OpenClaw updates its protocol quarterly, so keep automatic updates enabled. When upgrading manually, always back up your configuration file to avoid losing custom settings.
