Unavailable.[Session:User: ActiveDirectory\User].
Unable to reach Excel Calculation
Services http://Servername:32843/aaf0ae2450e64fa088df4fbcbaf32bb7/ExcelService*.asmx.[Session:User:
ActiveDirectory\User]
Cause of error:
Application pool on WFE server get stopped causing requests
generated from this particular machine to time out.
Application pool stopped because the service account used to
configure Excel Calculation services was no more member of the local Administrator
group.
Service account used in application pool should be there in
Administrator group.
Excel Calculation services requires permission on Office
Server\15.0 register value to perform excel operations. As registry values has
only administrator permission, so the exclusion of service account from
Administrator group do not allow it to perform its tasks.
Solution:
Added service account to local administrator group.
Restart “World Wide Web Publishing Service”.
