This page focuses on solving common multiplayer and online connectivity problems.
If you are having trouble hosting or joining games:
- Confirm all players are on a similar game version or build.
- Check that everyone has a stable internet connection.
- Prefer Ethernet for hosting when possible; avoid weak Wi‑Fi.
- Temporarily disable VPNs or proxies to see if they are causing issues.
Multiplayer connections can be affected by network configuration:
- Strict or symmetric NAT types may block peer-to-peer connections.
- Some routers or corporate networks block the ports required for online play.
- Firewalls and security software can silently block the game’s traffic.
If you suspect a network or NAT problem:
- Power-cycle your router and modem.
- Test from a different network (for example, a mobile hotspot) when possible.
- Check your router documentation for port forwarding or UPnP options if you are comfortable changing settings.
- Cannot join friend’s game – Confirm both players are online, using the same version, and not blocked by firewalls.
- Frequent disconnects – Look for unstable Wi‑Fi, heavy background downloads, or VPN usage.
- High ping or lag – Try playing on servers or hosts closer to your region; close background network traffic.
If problems persist after basic checks:
- Use the Multiplayer / online issue template in our public hub.
- Include platform(s) for each player, connection type (Wi‑Fi/Ethernet/mobile), and any VPN or special network setup.
- Provide clear steps to reproduce the issue (hosting, joining, region, number of players).
