I want to connect to the Windows Server. I used Remmina and Rdesktop but both of them occur error. I think this error is about TLS. How can I solve that? please help me. Thanks
Versions: Ubuntu 22.04.1 LTS Windows Server 2012 r2
RDesktop
Core(warning): Certificate received from server is NOT trusted by this system, an exception has been added by the user to trust this specific certificate.
Failed to initialize NLA, do you have correct Kerberos TGT initialized ?
Failed to connect, CredSSP required by server (check if server has disabled old TLS versions, if yes use -V option).
Remmina
