The "No protocol specified" message seems to be a bit obtuse.  I looked into 
it when it was reported here [1] (which of course I can't reproduce now :-( )

It comes back from the server when an attempt is made to open a connection, 
and really means something like "No authorization method specified" - the 
client didn't offer any authorization data and the peer address wasn't 
available or wasn't on the host access list.

I'm afraid I don't know why it happens.

I assume you are starting the server using startx or otherwise providing an 
-auth argument?  A workaround might be to not to do that.

It might be informative to see if anything relevant is logged with '-audit 2'
