Handle state – limits reached

[datapata]

Hello! I saw another post with a similar scenario after upgradering from Ubuntu 22 to 24. I’m running the free version and only connect one session at the time. If I have connected once and try to reconnect, the client see a never ending loading spinner. On the server side. I see log messages related to “limit reached”, but I have no active sessions from any client as far as I’m aware. Manually restarting nxserver through terminal will allow me to connect again.

Here is a chunk of the nxserver.log output during reconnect if someone is able to help me to interpret it:
