Problem to solve
Remmina currently unable to connect to Microsoft Servers where TLS 1.2 or higher for RDP /SCHANNEL /SSL is enforced.
Microsoft native RDP client can connect to enforced servers.
Further details
Error displayed in the GUI:
Could not connect to the RDP server “10.4.53.34” via TLS. Check that client and server support a common TLS version.
I just installed a Windows Server 2012 R2, and I was not able to connect via RDP until I configured Remmina to use TLS level 0 – which I’m understanding is not exactly TLS 1.2, and not so secure:
