“502 connection failed” and other 502 errors explained – and resolved

Web servers show 502 errors when they are unable to display a requested page – due to network error, security restrictions, and so on.

502 Connection failed is one such error reported by Fiddler, a web app debugging tool.

It means that Fiddler’s request for a web page was blocked (or request delayed) by the site’s web server or firewall or load balancer, causing the request to timeout.

There could be other reasons also for this issue.

Here at Bobcares, we help website owners resolve server errors as part of our Outsourced Technical Support services.
