Can you curl localhost:3334?
Discussion
No it returned
curl: (7) Failed to connect to localhost port 3334 after 0 ms: Couldn’t connect to server
that confirms that it's not running or was unable to bind to that address/port
try running
sudo systemctl status
it may give you more information, there is also
sudo journalctl -u
Thank you. I tried the systemctl status command and it looks like it’s not running
the journalctl command often shows more context and if you read it carefully you may see something, like "permission denied" on reading or writing some file or folder or binding to an address
