I seem to be having the strangest issue with my Plesk hosting. The system was running fine for a year. Then all of the sudden, most of the sites started showing the message "Bad Gateway 502 - Nginx".
After extensive research the only option to get the site working again was to remove "Nginx" from hosting. That seems to work for a little amount of time. I'm not sure on the timing but after some amount of time, some of the sites start to show the same error message again.
I reinstall...
