An ASP.NET application published to IIS on a server on port 81. The app calls external data provider over http (call), using a proxy.
The app runs fine locally, but it fails on a server. When I'm logging in to the server I can make the call using http://localhost:81/, http://servername:81/ doesn't work neither from the server nor outside of. Note, server name is resolving, we've some other apps making no external calls they work fine.
The exception I'm getting is:
System.Data.Services.Client.DataServiceQueryException: An error occurred while processing this request. ---> System.Data.Services.Client.DataServiceClientException
I tried changing the app pool user for the application and which only temporary fixed the problem then it re-appeared (group policies?).
Can anyone help us resolving the problem?
