For some reasons specific clients are getting 502 error. I've checked /var/logs/nginx but this folder is literally empty. The php-fpm log in /var/logs/php-fpm contains error.log, it asked me to increase pm.start servers which i did.. Now there is no errors appearing in the logs, but it still throws 502 for clients? Not all, but only some clients. I did update recently the php, to include GD. Not sure if that could be why.. webp support, which @eva2000 added to the beta 01.
