Ubuntu Telnet Connection Error: 'No route to host'

It seems like the connection to the server pz1943.xyz on port 3002 is not possible from your machine. The error message 'No route to host' indicates that there might be a network issue that is preventing the connection. You may try the following steps to troubleshoot the issue:

1. Check if you have an active internet connection by opening a browser and navigating to any website.
2. Verify that the server pz1943.xyz is up and running by pinging it from your machine using the command 'ping pz1943.xyz'. If the server is down or unreachable, you won't be able to establish a connection.
3. Check if there is any firewall or security software on your machine that might be blocking the connection. If so, you may need to reconfigure it to allow the telnet connection.
4. If none of the above steps work, you may try connecting to the server from a different network or machine to see if the issue persists.
