502.3 Bad Gateway “The operation timed out” with IIS Application Request Routing(ARR)
When working with ARR deployments one of the errors you might see is 502.3 Bad Gateway. The 502.3 means while acting as a proxy ARR was unable to complete the request to the upstream server and subsequently send a response back to the client. This can happen for multiple reasons including , failure to connect to the server , no response from the server, or server took too long to respond (time out).
