The connection with the server was lost. Error is 108: Connection reset by peer

[eshama]

Hi,

I was wondering if I could get some help. I tried logging into one of my servers and received this error message. I am using the free version on Linux. The problem is with a virtual display.

The server is OS is SLED15 and I am connecting from a Windows 10 machine .

I would appreciate any help I can get, thanks.

I’ll as the same question that I asked in your other topic (https://forums.nomachine.com/topic/the-session-negotiation-failed-error-node-was-not-retrieved):

I assume you are using the latest version on the SLED host. What desktop environment are you connecting to?

[eshama]

Yes I updated the NoMachine software on the SLED machine that I am trying to connect. I’m sure what you mean by desktop environment. I have tried to connect to the SLED machine through both PC and Ubuntu and neither are working and I am receiving the same error.

Eshama, what desktop environment (DE) is running on your Linux SLED ie. is it Gnome, KDE, LXDE, something else? Is it the NoMachine Free Edition running there? Were you able to connect before?

We are not aware of similar problems with Suse or Ubuntu.

Hello,

I think it is running Gnome. Yes it is the Free edition. Yes I was able to connect until recently.

Let me know if you require any more info.

Thanks,

Ethan

I would like to confirm that I have the same problem.

I have figured out that I’m only getting the “connection reset by peer” issue if the screens on the host machine are currently locked (the user locked the screen, or the screensaver locked it due to inactivity). If the host screen is unlocked, the client can connect without any issues.

The host is running Ubuntu 22.04 LTS, NoMachine 7.10.1 Free version.

I have collected the debug logs and have mailed them to the specified address.

Please show us the output of:
$ sudo netstat -anlp | grep egl

If it’s empty,  enable egl capturing with sudo /etc/NX/nxserver --egl-capture yes. What does the output of grep egl after enabling? (this is to check that egl capture is being pre-loaded).

Then, on the server, log out from the desktop, log back in and then start a NoMachine connection. What happens?

[jj]

The grep command shows nothing, but that doesn’t change after enabling it with the --egl-capture argument.

To follow up, I have since rebooted the machine for unrelated reasons, and when I checked netstat for egl again, it was clearly loaded.

Since then, NoMachine works perfectly fine, so this is obviously the solution!

Thank you very much!
