Version Mismatch
A version mismatch happens when your game client and server are running different versions. This prevents connection.
What is Version Mismatch?
Section titled “What is Version Mismatch?”Games require the client (your game) and server to run the same version. When they don’t match:
- You can’t connect
- You see errors like “Outdated server” or “Incompatible client”
The fix: Make the versions match — either update your client or change the server version.
Quick Diagnosis
Section titled “Quick Diagnosis”| Error Message | What It Means | Who Needs to Update |
|---|---|---|
| ”Outdated server” | Server is older than your client | Server owner updates server |
| ”Outdated client” | Your client is older than the server | Player updates game |
| ”Incompatible version” | Major version difference | Either side — match versions |
