I will be share experience that once we completed upgrade Successful and by hearing sound my service is not working. I will be sharing experience that SQL server was upgrade 2014 SP2 To 2016 and Upgrade completed once report to office found that SQL report service stop responding.
Issue reported: While access URL getting error failed to load expression host assembly
Error; Failed to load expression host assembly. Details: Could not load file or assembly 'SrsResources, Culture=neutral' or one of its dependencies. The system cannot find the file specified. (rsErrorLoadingExprHostAssembly)
While seeing cm console we have seen without report url
This error report normally after upgrade below are the key possibility
Point 1: Connection got broken between cm SERVER to report server
Point 2: If any access has been revoked from existing service
In my case I found that remove report service and reconfigure report service work fine.
