WSUS Connection Errors

Question

Hi All,

We have a WSUS server which is having issues connecting and unable to get any updates. The firewall have been configured to allow outbound requests to Microsoft URLS on port 80/443. I can see traffic going out to update.microsoft.com. Have tried pointing server to proxy but getting unable to connect to remote server. Does anyone know what these errors mean and how to resolve?

1. Error without Proxy

WebException: The request failed with HTTP status 404: Not Found.

   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.SyncConfigUpdatesFromUSS()

   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.ExecuteSyncProtocol(Boolean allowRedirect)

2. Error with Proxy Defined 

WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 52.152.180.151:443

Any help appreciated.
