Launcher: Protocol error on RDP connection

Launcher: Protocol error on RDP connection

Hi Support,

When we try to connect to a RDS (admin session) server (member of a RDS cluster) we are getting a protocol error.

"Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again."

I've found the same error for RDM. (https://forum.devolutions.net/topic24664-protocol-error-for-rdp-sessions.aspx)

But it always happens, even when no other sessions are open. (and their isn't a 64bit launcher)

We allready tried to change the RDP version, but without success.

Some time, (1 out of 100 I guess,) the connection succeeds.

When using the normal RDP client to connect to the server with default settings every works fine.

Kinds regards,

Hans Vos

Hello Hans,

Which version of RDM are you using? If you are using the enterprise edition of RDM please confirm you use C:\Program Files (x86)\Devolutions\Remote Desktop Manager\RemoteDesktopManager64.exe

Hello David,

None, we are using the Launcher with the password server.

We don't use the RDM.
