nmap <IP-ADDRESS> -- list ports
Well, there are a few things you can check: Are you querying the right port on the client side ? Is your service started ? Is it listening on the right port ?
Those three questions will generally help you solve your issue.
Quick generic command to be entered on the server (the machine that runs the service)
Checking that the service is listening on the expected port
ss -nat | grep <enter port number here> | grep LISTEN
Some people on older systems might also use this
netstat -an | grep <enter port number here> | grep LISTEN
If you don't see anything here that looks like your port number, your service is either not started or not listening on the port number you specified.
Checking that the service is running
service <service name> status
