API Connection Problems Diagnostic Manual
Step-by-step troubleshooting recommendations:
- Basic validation: Check whether the API key has expired (the validity of the key varies among platforms) or there is a character input error.
- network diagnosis: Confirm that you can ping the target domain name such as api.openai.com through the "Network Test" module.
- Quota check: Log in to the back office of each service platform to confirm the remaining call quota (especially the free version of the API often has a limit on the number of times)
- log analysis: Check error_log.txt in the Omnitool installation directory to get detailed error codes.
For complex problems you can take: 1) try to verify service availability by calling the same API directly with Postman; 2) temporarily disable the firewall to test if the request is blocked; 3) update Omnitool to the latest version to get the bug fix. Most connectivity issues can be resolved by updating the key or checking the web proxy.
