Your session ended because an unexpected server authentication certificate was received from the remote PC.
You might be receiving this error because your RD Web Client Broker certificate has expired. You may have placed the new certificate at RD Gateway, Web Access and connection broker using RDS Deployment properties but missed to import the same for RD Web Client via powershell. If that is the reason the below steps can fix it quick.
- Export your SSL certificate to DER format (cer/crt) from your certificate store using MMC.
- Open powershell Import certificate to RD Web Client Broker using below command.
Import-RDWebClientBrokerCert <path-to-your-certificate.cer>
