Created a new SL 2015 CU2 server installation for a client to replace their existing one. Basically replicated the old environment on the new one (not an upgrade). Installed all the same CU2 build and Hot Fixes as on the old environment.
New server runs Application Server (as does the old one) for Quick Send. At times, the new server build experiences the following error:
Microsoft.Dynamics.SL.AS.DevObj
Error refreshing Application Servers: Connection Timeout Expired.
If we click the OK button, AS resumes it processing of QS jobs. But someone has to monitor the AS job to make sure there are no errors, and QS jobs get backed up until OK is clicked.
Not sure what to check to determine the cause of the timeout.
