Resolved 502 Bad Gateway on Plesk 12.5.30 #39 and Ubuntu server 14.04

[Boris Panno]

Hi all,
the problem in the title is randomly. Above all at login to some sites made with Prestashop in the Front-end.
I could not figure out the source of the problem from the log files.
Can anyone give me any suggestions where can I look for the problem to solve it?
Thank you all in advance.

Hi Boris Panno,

"502 Bad Gateway" - "nginx" - issues are mostly caused by missing or incorrect nginx directives, or as well by inactive services. Pls. be aware that there might be quite a lot of reasons, which you should investigate with the help of your domain - specific log - files:

Plesk for Linux services logs and configuration files ( KB - article: 111 283 )​

You will find an awfull lot of "502" - issues/problems, when you use the Forum search. Pls. have a look at: https://talk.plesk.com/search/search?&keywords=502+bad+gateway
