Bluemap Viewer server crashes on startup – what to do?

Bluemap Viewer officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.6, 1.20.5. 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 Bluemap Viewer – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Bluemap Viewer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
