Frequently Asked Questions

Saros Mod Checker 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 Saros Mod Checker compatible with forge and neoforge?

Saros Mod Checker officially supports forge, neoforge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Saros Mod Checker – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Saros Mod Checker consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
