I Can't open port 30120 - Ubuntu Server 16.04

I want to host a FiveM server on my VPS, but I'm unable to open a port for this (30120). I've already added a rule to UFW and iptables, but I can't still pass the nmap test. Here is what i got:

Starting Nmap 7.01 ( ) at 2017-10-06 14:53 CEST

As you can see port 30120 is filtered and the reason for this is that it can't determine route (I'm not sure what does it mean). UFW and netstat -aunt says that I'm already lisening on this port

And here is the netstat output (xxx.xx.xx.xx - IP adress of my VPS):

I also have this port opened in iptables

Does someone have any idea why this port is still closed?
