502 Bad Gateway

Hello,

I have an issue with one site on my server (502 Bad Gateway)

I have tried these commands:

Code: [Select]

sh /scripts/restart_cwpsrv
systemctl restart cwp-phpfpm
systemctl restart cwpsrv-phpfpm
sh /scripts/update_cwp

/usr/local/cwp/php71/bin/php -v

I have tried to removed Mod Security and disabled it for that user

When I checked the logs I found these errors:

Code: [Select]

Can anyone help me with tis issue?

I'm using Nginx + Varnish + Apache PHP-FPM Performances as a webserver

Thanks.

Hi, why do you checking CWP if you have a problem with a website? Do not understand...
First of all, you have to check the website log file in /usr/local/apache/domlogs/ . There too many reasons for the 502 error, I guess you use PHP-FPM which stopped. Try to change it to apache+nginx+php-cgi (for example) via WebServer Domain Conf in CWPadmin, WebServer Settings
