Not working with remmina with rdp Gateway #41

Closed dsrinibanyan closed 1 year ago

dsrinibanyan commented 2 years ago

Hi there,

Very useful project. I appreciate the effort her. I was trying to use this implementation on linux and tried rdp with remmina. But it seems to fail due to NTLM negotiation failures. I see people getting it to work, not sure what am I missing. Plz help.

Try FreeRDP.

If you can connect, it may be the problem of remmina itself. The problem recurs when connecting to Windows10.

I fixed the issue. That's because freerdp expects NTLM exchanges. But the same is not required on windows/mac rdp clients.
