ok,is the port 30120?
yes it is
ok,wait
Were you able to connect to server?
Yes,I can connect to the server
Thats strange, cause I cant see the whole server in the list or direct connect
server list maybe is something wrong with it
Direct connect is still work fine
You can try to redownload the Fivem
Yeah, or just clear cache. Well, now I know that other players can connect to my server, so problem is solved, if there ever even was any problem 
Just wait for the server list come back
