Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 504

Hi All,



Found the issue.

It is because of the local network proxy.

504 timeout is from proxy.

So if any of you came across this same issue, please try by passing the proxy and see.



Hope this post will help someone out there.
