<p style="margin-top:0; margin-bottom:0"><span style="font-size: 12pt;">I'm having problems reconnecting to any existing sessions on a specific x2goserver instance from any client I've tried. If I kill the existing session using x2goterminate-session and create
a new one the new one connects with no problems, but if then I disconnect from it and attempt to re-connect (even from the same client), then again I get the same problem -- client does not connect, and message is displayed in client "</span><span style="white-space: pre-wrap; font-size: 12pt;">The
remote proxy closed the connection while negotiating </span><span style="white-space: pre-wrap; font-size: 12pt;">the session. This may be due to the wrong authentication

the problem go away. </span>I also tried removing ~/.x2go and ~/.x2goclient directories on client and server and allow them to be recreated, but this did not change behavior.<span style="font-size: 12pt;"></p>
