Prominence II: Hasturian Era · Java 1.20.1
Troubleshooting
Common fixes for joining and playing on Prominence II servers — plus a few server-owner fixes for crashes and hosting panels.
Fix: ‘Outdated version’ / ‘illegal reupload’
Reinstall from the official modpack listing and make sure your profile matches the server.
Fix: Exit Code 1 (crash)
Quick crash checklist: 8–10GB RAM, remove shaders/extra mods, and reinstall cleanly.
Fix: Shaders / Iris crashes
Disable shaders first, update GPU drivers, then re-enable carefully with a compatible shaderpack.
Fix: Can’t connect / connection timed out
Check IP/port, server status, firewall, and (for home hosts) port forwarding + CGNAT.
Fix: ‘Can’t keep up’ (TPS) / performance tips
Quick settings that reduce stutters and improve stability on modpacks.
Server crash: entrypoint stage 'main'
Usually caused by client-only mods or installing the client pack on a dedicated server.
Server: missing datapacks (OpenLoader)
Restore server pack files (openloader/config) and avoid partial updates.
Hosting providers: modpack update issues
Fix broken one-click updates by reinstalling the server pack or pinning a stable version.
