StacKit server crashes on startup – what to do?

StacKit officially supports fabric for Minecraft 1.21.3, 1.21.2, 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with StacKit – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if StacKit 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.
