API integration: LIMIT_CONN_LINE connection blocks during bulk calls

POSTED BY: sysops_expert ACTIVE_MEMBER POSTED ON: Jun 23, 2026 CATEGORY: GENERAL

Our API calls trigger suspensions when running billing commands because the Nginx rate limiter treats external panel API requests as DDoS. How do we whitelist the API client IP?

The configuration script checks for Nginx rate limit connection settings. Make sure `/etc/nginx/conf.d/limit_conn.conf` does not block internal proxy queries. You can whitelist your client IP inside the geo block in `/etc/nginx/nginx.conf`.

I rebuilt the panel settings and verified the limit_conn.conf was created. The API module runs now without timeouts.
