I was wondering whether it has something to do with the firewall ports on my CentOS machine that NoMachine is listening for? As a further troubleshooting step I tried, I can connect to the Linux machine if I use a reverse SSH tunnel and connect to my own local port instead but I’m not sure if this helps.Īll NoMachine installs are running the free version. I can still access the Linux machine via SSH in a terminal from the Windows machines, so I know that the IP is still valid.

My laptop via VPN also has the same error.

I can connect to my Windows machine from my Linux but not from my Windows machine to my Linux I get a connection timeout error. In the case of the two workstations, the Linux and Windows machine seem to be able to detect each other in the client. It seems both Windows machines cannot connect to the Linux machine any more using my existing settings. Now, I can only access the Windows workstation. I used to be able to access both from my laptop with the VPN enabled (I guess for the correct IP routing). The Linux and Windows workstations are behind a firewall. My Linux (CentOS 7 GNOME) install updated to 6.7.6 since last night and I’m now having issues connecting from my 2 Windows 10 machines which worked fine before (one is a workstation on the same network, the other is a laptop I use via a VPN).
