Ubuntu – Cannot RDP to Windows 7 with Remmina on 12.04


Since I upgraded to 12.04, I am unable to RDP to a Windows 7 server. All I can see is a pop-up that says "Uable to connect to RDP server ". I am able to RDP using Vinagre, so that rules out any issues with my router or the Windows server.
As far as I can tell, there are no logs from Remmina and the Debug window shows a blank.
Any one got any ideas?

I too had the problem that I could connect to a Windows 7 machine and suddenly (after weeks) I got this error: Unable to connect to RDP server

In my case I deleted the entry from ~/.freerdp/known_hosts and it then worked fine.
