I need some advice on what to do when receiving a 502 Bad Gateway from my IIS web server. When visiting my webstie via http://localhost or 12.7.0.0.1 it will work perfectly fine. When visiting it by my IP it won't work at all, and my CDN returns a 502 Bad Gateway. I am using Cloudflare as a CDN.
It was working perfectly fine 2 hours ago, when all of a sudden it stopped working. I have made sure that the Windows Firewall isn't blocking it in any way. What else can I do?
It is NOT the cloudflare-nginx error, its coming from IIS. I have checked the error logs in IIS but nothing recent. The most recent logs display this:
