Issues with Linux remote access and SSH occasionally occur without clear causes.
You're facing some tricky remote access issues with your Jellyfin server. It sounds like the problem is related to how the system handles authentication and session persistence. Since you're using a dummy monitor and remote desktop, the connection might be dropping unexpectedly. Trying to restart with SSH also isn't working, which suggests the service might not be properly configured for remote sessions. You might want to check if Jellyfin is using a specific configuration file or service that needs to be restarted, or consider switching to a different distribution that handles remote connections more reliably.
Consider using VNC with a virtual desktop instead. If it's a server, you might not need a desktop environment at all. Try connecting via SSH with the "-vvv" option so you can see the problem clearly. It could just be a network-related issue as discussed before.
It seems the server isn't running or isn't set up to accept connections from the 192.168.0.0 network. There are many guides available on configuring sshd, including those that explain public/private key authentication for added security and convenience. After setting it up, you'll likely need to configure a VNC server—choose one that fits your operating system. Personally, I've relied on Webmin for tasks that would otherwise require terminal commands for about fifteen years. While security concerns are raised, it's mainly usable from within the system; if someone gains access, it should be restricted to internal use only. Regarding security, if the service is only accessible internally, you can connect remotely to X and launch a VNC session directly on your local machine. This way, the session runs in a real window rather than a fake display. Many warnings about security issues are discouraged when the system is on a private network, as access is already managed. When someone claims something isn't safe, verify the situation and ensure they understand the context rather than just repeating generic advice.
Ubuntu version 24.04 LTS includes headless support for GNOME RDP added in GNOME 46. Ensure OpenSSH is installed, activated, and permitted via firewall with the specified commands.
It suggests the IP address of the device you're attempting to connect to might have been updated. If not, examine the logs for the ssh server using systemctl status sshd or journalctl -u sshd to understand the issue.
