I had the same experience *without* any upgrade to Ubuntu.

The Remmina client simply stopped working one day.

Today I spent several hours on a Windows 7 box trying to work out why
"Unable to connect to RDP server".  Was it the Windows firewall?  Was it
McAfee being expired?  What does the Windows event log tell us?  (It
tells us there's a connection, a session is started, and then it's
disconnected.  Nothing useful.)  Was there an authentication problem?
How about connecting with no user/password?  Was it some obscure need-
to-login-at-the-console-first session problem (as happens with SSH
sometimes).

No, in the end the forums gave the answer: It's Remmina, not Windows.
Delete ~/.freerdp/known_hosts and it'll work.

I just removed one line from that file, and all my problems were solved.
Meanwhile the changes to Windows to try and find the problem were a
waste of time and maybe not such a good idea :-)

I don't know what went wrong with the signature in
~/.freerdp/known_hosts - as I didn't upgrade the Ubuntu client, and I
didn't do anything on the Windows box either (it's been running for
years).

The only thing I'm aware of is Windows 7 rebooted itself after an
automatic update somewhere between Remmina working and not working. But
even reboots don't normally cause this problem.

I think this might have happened for me once before.  Like #27, the
workaround is hard to remember because the error message doesn't say
anything useful.

This is on Ubuntu 13.04, remmina-1.0.0-4ubuntu2,
libfreerdp-1.0.1-2ubuntu1.

Thanks.

Title:
  Cannot connect to RDP if host fingerprint changes

Status in remmina package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to Precise, all my existing connections for RDP are no
  longer functional.  I get the following message:

  Unable to connect to RDP server XXXXXX

  All connections are in a windows domain.  Have tried various O/S's;
  Win 7, XP, 2008 R2.  Same result.  Have tried RDP, TLS, NLA and
  Negoitate.  All systems are set to allow all types of RDP traffic.
  Have verified that the systems are up and function from a Win7 Vbox.
  Tried creating a new connection, same result.

  
  Anything else that would be of help?  Debug info attached. (Hopefully)
