MacOS Mojave – No sessions available

[vertico]

Hello,

I’m running NoMachine 6.5.6 on a couple remote hosted macOS machines running Mojave.

About once a week on one of them I receive a “No Sessions Available” message when trying to connect.

Restarting the remote machine over SSH appears to resolve the issue.

Does anyone know what might cause this?

Hi, can you update to 6.6.8 and let us know if the problem is still there?

Hi,

I am having a similar problem. I installed the free NoMachine 6.7.6 recently on my Mac (MacOS 10.14.4) and on a headless Linux machine (Debian GNU/Linux 8.11). Our IT administrator did the latter, as I don’t have administrator rights for the server.

NoMachine worked fine for several days and suddenly I only got the progress wheel when trying to connect to my server (“Connecting to server”). Restarting the software and my computer did not help, so I killed all NoMachine related processes under my user account on the server. Now, when I connect and after inserting my password, I get the message “No available sessions on this server”, but I can’t create a new session.

Restarting the server is not an option for me as this is a shared computing server.

Please help!

 

Thanks,

Nikolas

Nikolas, can you send us logs from the Linux host?

Sent. I hope this will be helpful.

Hello.

Thank you for the logs.

It seems you have encountered a bug in the cleaning old connection procedure. We are investigating it further.

Unfortunately right now the only way to fix it would be to restart the NoMachine service by running:

# /etc/NX/nxserver --restart

/Mth

Thanks for your reply, Mth.

It worked at first, though the command is:

/etc/NX/nxserver --restart

However, after I was able to create a new session, I exited it again and now I’m in the same situation again. I guess another restart of the NX server will be necessary every time a new session should be created.

Cheers,

Nikolas

 /etc/NX/nxserver --restart 

The problem is that — has to be enclosed with the ‘code’ tags which I have now corrected in both Mth and Nikolas’ posts 😉
