Dying Light Co-op Not Working on PC: Checklist
Verify both players own compatible PC versions, have completed required introduction steps where applicable, and have stable network access before diagnosing firewall settings.
Quick answer
Verify both players own compatible PC versions, have completed required introduction steps where applicable, and have stable network access before diagnosing firewall settings.
Confirm game progress
Some games restrict co-op until a specific early story section is complete. Check each participant’s in-game session settings and mission state.
Match installed versions
Install pending updates on both PCs and disable incompatible mods during troubleshooting. A mismatch can prevent joining or cause a session to fail after connecting.
Test basic connectivity
Restart the game and network equipment if necessary. Do not forward random ports or disable Windows Defender Firewall without a documented reason.
NAT and matchmaking
When direct joining fails, check the game client’s current online-service status and follow the platform’s supported NAT troubleshooting instructions.
Recheck after changes
Only modify one setting at a time. Confirm whether the same invite path works after each step so you can isolate the cause.
