    Hi, I have been using NoMachine for a few weeks without problems now, but lately, when I try to connect remotely to my computer, I get the issue : “Session negotiation failed”, but I am still using the same computers on both ends, and there has been no major updates.

    When I looked into the connection journal, I got the following issue :

    Erreur : Impossible de créer la session. L’erreur système est : %s’.

    Info: Connection to 10.96.185.139 port 4000 closed at 09:37:11 605.405.

     

    I already tried uninstalling and reinstalling NoMachine on the remote machine. I also made sure that the remote machine was up and running. Could you help me resolve this ?
