Frequently Asked Questions

MCMultiplayer server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is MCMultiplayer compatible with forge?

MCMultiplayer officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with MCMultiplayer – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if MCMultiplayer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
