Any related error in Nginx log files (/var/log/nginx/*.log)?

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Having the same problem on CentOs 7

nginx error.log shows:

2020/06/30 19:25:28 [error] 588#0: *573 connect() failed (110: Connection timed out) while connecting to upstream, client: XXX.XXX.XXX.XXX, server: _, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9999", host: "www.mydomain.com"

Nothing has changed on the server, yesterday working amazingly well, today 502 Bad Gateway error message, then it starts working fine for like 2 minutes and then again 502 bad gateway error.

Please help

I can copy or send you all the logs that you would need, i don't see anything odd in the log files, just the nginx error log.

Nothing has changed or have been installed in the server. It just stop working from one day to the other one, if you need access to the server pm me and i will send you the server info.

Re: Can't access my other website Error 502

I ran systemctl list-unit-files | grep -E 'php[^fpm]*fpm' and showed me this:

php-fpm.service                           enabled
php71-php-fpm.service                     enabled

Is it normal to have those 2 php-fpm services enabled? shouldn't it be just one?
