Hi,

Logs checked /home/users/user1/logs/domain.com/access.log shows:

Code: Select all

xx.xx.xxx.xxx - - [07/Oct/2025:10:02:50 +0100] "GET /index.php?action=json HTTP/2.0" 200 299 "https://domain.com/index.php?link=3" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/141.0.0.0 Safari/537.36" 503 358
xx.xx.xxx.xxx - - [07/Oct/2025:10:03:36 +0100] "GET /index.php?action=json HTTP/2.0" 200 299 "https://domain.com/index.php?link=3" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/141.0.0.0 Safari/537.36" 503 335
However, in
/home/users/user1/logs/domain.com/error.log there are no logs showing the cause for the 503 error.

Is there any settings somewhere in keyhelp I can enable more verbosity in the logs to pinpoint the issue?
Maybe modify php fpm conf to add more logging?

The server is not under load at all and not many visitors either, so it's not a capacity issue.

Thanks

Hallo,

when it is an internal error of your CMS then you should enable Debug Mode. Many CMS also provide there own log
