Suddenly getting a 502 Bad Gateway error

Question

My boss was f***ing around with this page and suddenly it stopped working and started giving us a 502 Bad Gateway error. Is there anything you can see that explains why this happened?

Answer 1

A 502 Bad Gateway error is not caused by static HTML like you just displayed.

The server was probably having an internal error or an error communicating with other servers - maybe there was a (temporary) overload, or another server/service was not reachable. Does it still happen when you clear your cache or use another browser/computer?

Can you tell us more about your webserver, and its links to other servers/services?

Answer 2

The cause for the 502 is not on the page. Looks more like a configuration issue, either on the server or on a network component (router).
