SRCDS Trouble

I’m trying to host a dedicated server and it seems my friends are unable to join me, “failed after 4 retries”.

Need more information.

Are they trying to connect with your external IP?
Does your router have the proper ports forwarded?

I’ve forwarded ports 27015-27016 and they have attempting to connect to my ipv4.

Your ISP may not allow server hosting and put you behind a strict NAT.

I’ve fixed it, my open ports were both set TCP. I’ve since set one to UDP.
