I have just set up a web farm with Application Request Routing on IIS 8.5, with Load Balance connecting to two servers. The static page HelloWorld.html and the first login page looks fine. However when the submit button is hit, whenever a code behind is involved it takes a long time to load. I've modified the timeout value from 30s to 300s, then it loads for a few minutes and gave me a

502 - Web server received an invalid response while acting as a gateway or proxy server.

I've enabled trace log but not sure where can I find the exact problem. In the summary it's showing

MODULE_SET_RESPONSE_ERROR_STATUS

ModuleName ApplicationRequestRouting

Notification EXECUTE_REQUEST_HANDLER

HttpStatus 502

HttpReason Bad Gateway

HttpSubStatus 3

ErrorCode 2147954430

SET_RESPONSE_ERROR_DESCRIPTION

ErrorDescription The connection with the server was terminated abnormally

Anyone had similar experience and is able to give me a hint?
