I have installed SQL Server Reporting Service 2016, and suddenly, I got this error 'The report server was unable to validate the integrity of encrypted data in the database. (rsCannotValidateEncryptedData) keyset doesn't exist' when opening the Report Server Web Service URL.
I have also tried to open the SSRS Report Manager URL and I got a similar error as below
You specified a connection to a report server database that contains encryption keys for another report server.
If you are configuring a scale-out deployment, that feature is not supported by this edition of Reporting Services.
If you want to use this report server database with the current report server instance, remove the existing encryption keys first.
Any help, please?
