Subject: Bug#323: x2go server refuses client with 'Error: Wrong version or invalid session authentication cookie.'

My error was the same:

Error: The remote NX proxy closed the connection.
Error: Failure negotiating the session in stage '7'.
Error: Wrong version or invalid session authentication cookie.

I solved it in my case.

The reason was a wrong writing permission in the appropriate
directory where the client logged in. This is certainly not a bug but a
mistake, - and a trace to look at for the the one or other case with
this error.
