Hi, my site stopped working about 9.37 PM yesterday. Since then CPU activity is at 0. Site in web browser does not respond and user recieves 502 Bad Gateway, however deployments are active and deploy logs seem to be clear.

I haven't change anything in my deploy sice 3 months ago. Ports are set up the same way they were when the site worked. It aso isn't the issue of heavy load.

What can i do now?

Thanks for your help in advance.
