Troubleshooting
"Error connecting to server"
Make sure you're online and launched via run.bat. If it persists, the server may be restarting — try again shortly.
Wrong Java version
If the client won't open, you're likely on Java 17/21. Install Java 11 and ensure it's first on your PATH.
Mouse clicks land off-target
That's Windows display scaling. run.bat already fixes it (DPI-unaware mode) — just always launch through it, not the jar directly.
Stuck on "Checking for updates"
First connect streams the full cache over the internet — it can take a minute. If it never moves, confirm the server IP in run.bat.
