Report Server Custom Authentication is not Working I got 500 internal Server Error

[sowmyaKrishna]

Hi @Jon-Heide @riccardomuti 

I got 500 internal server error.

Logs are showing "Exception: System.Web.HttpException (0x80004005): Unable to validate data. at System.Web.Configuration.MachineKeySection.EncryptOrDecryptData(Boolean fEncrypt, Byte[] buf, Byte[] modifier, Int32 start, Int32 length, Boolean useValidationSymAlgo, Boolean useLegacyMode, IVType ivType, Boolean signData)
at System.Web.Security.FormsAuthentication.Decrypt(String encryptedTicket)"

but I added machinekey in value in rsreportserver.config

Please give me the solution

Thanks in advance...
