Issue EOL 12.5 on 01/01/19 - getting 503 errors.

[viziony]

Starting on 1/1/19 @ 5:35 AM EDT, my website started to experience ngnix 503 communication errors. I tried restarting the Plesk service which does not help, I would have to manually REBOOT my linux server in order to restored connectivity. Connection on port 8880 basically is hung unless I restart. Is this related to the EOL on Plesk 12.5 and I need to go onto Plesk Onyx?

Can I just use the GUI Plesk Installer to perform this upgrade and also would this fix my 503 errors? I am having to reboot the server at least twice a day now since 01/01/19.

Receiving a lot of these within the logs when the connection issue happens :

939#0: *172418 upstream timed out (110: Connection timed out) while reading response header from upstream

Hello,

When this happens again, check if apache2/httpd are still running.

Also, check the logs:
/var/log/httpd/* or /var/log/apache2/*
/var/log/nginx/*
/var/www/vhosts/<domain_name>/logs/*

You may find more information there.

Can I just use the GUI Plesk Installer to perform this upgrade

Yes, but do a full backup/snapshot first.
