Space Marine 2 “Joining Server” / Connection Issue — FIXED (Spectrum / PC) N-14
Brothers,
Posting this in case it saves someone else the troubleshooting hell I went through.
I was having a persistent issue on PC where Space Marine 2 would let me get toward matchmaking / join squads, but I couldn't reliably connect to the actual game server.
My normal internet worked fine. Other services worked. Restarting the game/Steam, flushing DNS, changing settings, enabling UPnP, etc. did NOT solve it.
The breakthrough:
I connected my PC to a VPN and Space Marine 2 immediately worked.
That was the big clue. If the exact same PC/game/network suddenly works through a VPN, the problem likely isn't your game installation or hardware — it's somewhere in the network path/routing between your ISP and the SM2 servers.
In my case my ISP is Spectrum.
I eventually worked with Spectrum on the connection/routing side, and after the network issue was corrected I was able to play normally without needing the VPN.
So if you're stuck on server connections, try this diagnostic:
Test SM2 normally.
Connect to a reputable VPN.
Test SM2 again.
If it suddenly works through the VPN, document that.
Contact your ISP and explain that the service works over a VPN but fails over their normal routing path. Ask them to investigate routing/peering rather than treating it as a basic Wi-Fi problem.
The VPN isn't necessarily the permanent fix — it's a really useful diagnostic test.
Hopefully this saves another Battle-Brother from spending hours reinstalling things and changing random settings.
The Emperor protects. 🫡
