Frequently Asked Questions

U Team Core server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.1). You can switch loaders with one click in the panel.

Is U Team Core compatible with fabric and forge and neoforge?

U Team Core officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with U Team Core – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if U Team Core 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.
