Hi Kenny_I,
Based on the error message, the issue may be caused by the incorrect configuration of Claims to Windows Token Service (C2WTS). The C2WTS is required because the communication between the web front-end (WFE) and the Reporting Services shared service will
always be Claims authentication.
The domain account used by the Claims to Windows Token Service needs to be granted the following rights through the Local Security Policy:
Act as part of the operating system
Impersonate a client after authentication
Log on as a service
We can find these settings under Administrative Tools > Local Security Policy > Local Policies > User Rights Assignment. And we should add the service account to the local Administrators Groups ahead.
For more information, please see the following links:

Hope this helps.
