Server wont appear in main list

Hello,

I've tried everything but my server will not appear in the server list. I am using a VPS so ALL port are open (ive even checked with the company).

People can join the server using the ip but not in the list.


Start file:

./srcds_run -game garrysmod +maxplayers 16 +map ttt_minecraft_b5 -authkey PRIVATE +host_workshop_collection 510681197 -ip 198.20.92.9 -clientport 27050

Autoexec:

gamemode terrortown
ttt_postround_dm 1
sv_gravity 150
ttt_preptime_seconds 15
ttt_firstpreptime 40
ttt_posttime_seconds 20
sv_loadingurl "http://njgaming.tk/GMOD.html"
sv_region 255

server.cfg

hostname "[UK] NJGaming |Low Grav|FastDL|Active Admins|Custom Skins|Nathan and James"
net_maxfilesize 100
sv_lan 0


Any help is appreciated
