My server It does not appear in browser. My Hosting says that the problem is on the side of masterserver. What i need to do?

Firstly, make sure your server is on a base gamemode I.e Sandbox. You should also make sure there’s a valid map, making sure you have that installed in your 'dir/maps/ folders. If not, you can do this by the command line.

After, you want to look at your connection info, if you aren’t sure contact your GSP, but it should look something like ‘1.111.111:1111’.

Click, legacy browser, add server, find server and paste that IP IN.

Although, if you’ve just started up your server and you’re certain you’ve done it correctly, make sure to refresh the browser, they don’t update automatically/ live.

it all nice, not this.
