I will let the owner know about this and i will post here his reply.

Hello, i have problem with adding server installed on myarena hosting.

when i try add server, i am set parametres:

ip address: 46.174.52.2:27252
game type: sounter-strike source (old)

then it returns "Server accepted me / OK", and c360qtool connecting, but i cant found my server in setti monitoring and in "Internet" tab of game client.

Setti connected in setmaster on server and added in Masterservrs.vdf on client.

3 months ago it worked.

Then it must be port forwarding or firewall issue.

After your friend can join as well, then try to add your server in the masterserver again.

Are your firewall settings and port forwarding correctly set?

5 min, i reinstall os and reinstall serv. but i think for it's a hosting problem. coz i ez connect to server, my friend no.

Are your firewall settings and port forwarding correctly set?
