Servers not showing in game for some

Odd thing stated happening, must have been like this for a few days. I'm in Canada and I can see my servers in the game but fro some reason US players can't see them. EU can but they sometimes show and sometimes don't.

Everyone can however see the server through http for examples http:://totally.mofo.sexy or 158.69.121.24

Also this site doesn't not show my servers. http://dpmaster.deathmask.net/?game=xonotic

I can ping that site from my server so they are seeing each other.

Where do I start to trouble shoot this.

For those that can't see the servers in the server list can you manually connect to them ingame.

Ok Im stuck on this. Mario set up his own server in the server list and its also not showing up on the stats just like my servers. I can see stats.xonotic.org from the server , netstat shows the server ports as in use and the like to server stats is active.

Could the stats server not be seeing my server?

Ok so I found on in the server list, seems its filtered oldest new but looking at the last played dates they are 5 days ago which is when I set up the new server.

Well that was a explore the server CP page a little but more moment. I you are using a OVH SYS game server you'll have to look for Game Mitigation section and a tiny "see" text button next to it. This will have the firewall settings. There add what ever ports you need for Xonotic.
