remmina throws "cannot connect to the 127.0.0.1 rdp server" over ssh tunnel

Hello !

    Remmina is one of my favorite desktop rdp/vnc client. Recently it's stopped to connect to MS Windows 2018 terminal server over ssh. The real cause was issued by xfreerdp which is called by Remmina. The error from freerdp was as :

[10:54:28:752] [8718:8719] [INFO][com.freerdp.core] - ERRINFO_LICENSE_HWID_DOESNT_MATCH_LICENSE (0x00000104):The Client Access License ([MS-RDPELE] section 1.1) stored by the client has been modified.
[10:54:28:752] [8718:8719] [ERROR][com.freerdp.core] - rdp_set_error_info:freerdp_set_last_error_ex  ERRINFO_LICENSE_HWID_DOESNT_MATCH_LICENSE [0x00010104]

Running xfreerdp over strace lead to the file in the directory ~/.config/freerdp/licenses. I've renamed it, and after that the problem has gone (new license file was created).

Good Luck !!!
