docker build -t blockblast:7.6 . docker run -d -p 5000:5000 --name bb-server blockblast:7.6 Now the server is reachable at http://<host‑IP>:5000/hub . | Symptom | Likely Cause | Fix | |---------|--------------|-----| | Client can’t connect – “Handshake failed” | Server not listening on the right interface ( 0.0.0.0 vs localhost ) | Ensure you start the server with dotnet run inside the src/Network folder. Verify firewall rules allow TCP 5000. | | Blocks appear out of sync | Multiple clients using different game versions | Run git pull on all machines, then delete the /.godot/ cache folder and restart the editor. | | SQL exception “database is locked” | Multiple server instances pointing at the same SQLite file | Use a single server instance per DB file, or switch to PostgreSQL (see docs/db-migration.md ). | | Godot crashes on start (SIGSEGV) | Incompatible Godot C# bindings (Mono version mismatch) | Install Godot Mono edition, then run dotnet tool restore to align the SDK. |
