How to to fix Unhandled exception: System.TypeInitializationException: The type initializer for 'Microsoft.ReportingServices.Portal.Services.TelemetryService'

Question

Good day,

Users cannot access the SSRS report through the portal, this happened after the servers went offline due a UPS. Any way, When trying to access the http://servername/reports site, the RSPortal....log files has the following entry each time. I have tried everything short of an uninstalling and reinstalling SSRS. We are using version 14.0.600.1763. QA server with the same config is working perfectly fine after I restarted up the SSRS service and IIS.

Hi @Sphiwe Luthuli

I found this document about TypeInitializationException for you, maybe you can use it as a reference:https://learn.microsoft.com/en-us/dotnet/api/system.typeinitializationexception?view=net-8.0.
