OPenClaw Error Code Troubleshooting: Common Errors and How to Fix Them

OPenClaw, as a powerful data scraping tool, can occasionally run into errors during daily use. This article provides step-by-step troubleshooting for the most common error codes, helping you restore normal operation quickly and avoid workflow disruptions caused by technical issues.

Error Code 1001: Connection Timeout

When OPenClaw shows "1001 Connection Timeout," it usually means the target server is responding too slowly or your network has restrictions. First, check if your local proxy is set to global mode; if using a VPN, switch to split-tunnel mode or change nodes.

You can also reduce request frequency by adjusting the max_retries parameter to 3 in the OPenClaw configuration file and increasing the timeout value to 30 seconds. If the issue persists, try temporarily switching to a mirror address of the target source for testing.

Error Code 2003: SSL Certificate Verification Failed

Error 2003 often occurs when the target website uses a self-signed or expired SSL certificate. OPenClaw verifies certificates strictly by default; you can add --ignore-ssl-errors=true in the startup parameters to bypass verification. However, note that disabling certificate verification reduces security and is only recommended for controlled test environments.

A safer approach is to manually update the CA certificate bundle in your Python environment by running pip install --upgrade certifi and restarting OPenClaw. If the error persists, check your system time—time drift can also cause verification failures.

Error Code 3012: Cookie Expired or Missing

This error indicates that OPenClaw failed to carry valid cookies when scraping pages that require login. The solution is to obtain fresh cookies: manually log in to the target website, export cookies via browser developer tools, and paste them into the OPenClaw cookies.json file.

If you are running batch tasks, consider adding an auto-refresh cookie logic at the start of each session. You can also enable the auto_refresh_cookie option in the configuration, allowing OPenClaw to automatically re-login when cookies expire (credentials must be pre-configured).

Error Code 4025: IP Temporarily Banned

When you make too many requests to the same website, the target server may ban your IP and return code 4025. Stop the current task immediately and switch to a different proxy IP. OPenClaw supports dynamic proxy pools—you can list multiple available IPs in proxy_list.txt and set rotate_proxy to true.

Also, increasing the delay between requests is crucial. Set delay_min to 2 seconds and delay_max to 5 seconds to mimic human browsing behavior. If bans are severe, contact your service provider to request an unblock, or use residential proxies to reduce the risk of triggering bans.

Error Code 5030: Data Parsing Exception

OPenClaw throws error 5030 when it encounters unexpected HTML changes while extracting page structure. This is usually because the target website has updated its layout or enhanced anti-scraping measures. First, check if your selectors are still valid—inspect the latest page elements in your browser and fix the XPath or CSS selectors accordingly.

If the website uses dynamic content loading, switch OPenClaw's render engine to playwright or selenium mode and ensure the corresponding browser driver is installed. After modifying the render_engine parameter, rerun the task—most parsing issues can be resolved this way.
