Hosting Listen Server

Yeah I know there are a ton of threads regarding the same damn thing, I’ve read them.

Firewall - Fine
Router - Fine

“sv_lan 0
heartbeat” - Doesn’t work, not even for a bit.

I have recently downloaded the Stargate and Wiremod add-ons, I’m not sure if they would contribute to this problem or not.

So I’m wondering if any of you would know what would be causing this and how to fix it.
