Multiplayer connection errors in Palworld 1.0 usually fall into three categories: host session failures, join session failures, and password/server mismatch errors. This guide covers the most common errors and step-by-step fixes.
Common Errors at a Glance
| Error Message | Likely Cause | Fix |
|---|---|---|
| “Not Found Session 91” | Session no longer exists or network issue | Restart game, check NAT type |
| “Failed to Host Multiplayer Session” | Network session creation failure | Enable UPnP, forward ports 8211-8212 |
| “No password has been entered” | Password mismatch or version mismatch | Verify server version, reset password |
| “Lost connection to host” | Network instability | Check Wi-Fi, reduce player count |
| Infinite “Connecting” screen | NAT/firewall blocking | Forward ports, disable firewall |
“Not Found Session 91” Fix
This error means the game client cannot locate the multiplayer session. Try these in order:
- Restart both client and server. This clears temporary session cache.
- Check NAT type. Open Settings → Network → Check NAT. If it is Strict or Closed, you need to forward ports or enable UPnP.
- Verifyserver version. The host and all players must be on the same version of Palworld 1.0.
“Failed to Host Multiplayer Session” Fix
- Enable UPnP in your router settings. This allows Palworld to automatically open the required ports.
- Manually forward ports if UPnP is not available: TCP/UDP ports 8211-8212 to your PC’s local IP address.
- Add Palworld to your firewall exceptions — both the game exe and the dedicated server exe.
- If using a VPN or proxy, disconnect and try again.
Dedicated Server Setup Quick Guide
For a dedicated server with 32-player support:
- Download Palworld Dedicated Server from Steam Tools
- Configure
PalWorldSettings.iniinPalServer/DefaultConfig/ - Forward TCP/UDP ports 8211-8212 to the server machine
- Run
PalServer.exe— the server should appear in the server list - Join via the Multiplayer menu by searching for the server name
See the Dedicated Server Guide for detailed setup instructions.
Crossplay Issues
Palworld 1.0 crossplay is only available between Xbox and PC Game Pass. Steam is not crossplay-compatible with Xbox. If you cannot join an Xbox friend:
- Confirm all players are using Xbox or Game Pass version
- Add the host as a friend on Xbox network
- The host’s session must be set to “Friends Only” or “Invite Only”
See the Crossplay Guide for the full compatibility matrix.
FAQ
Can I play with more than 4 players?
Yes, through dedicated servers (up to 32 players). Standard co-op is limited to 4 players.
Does Palworld have crossplay between Steam and Xbox?
No. This is the most common source of confusion. Steam and Xbox networks are separate.
