RRDiscordBridge server crashes on startup – what to do?
Most common cause: wrong bukkit 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 (1.21.10). You can switch loaders with one click in the panel.
Is RRDiscordBridge compatible with bukkit and fabric and forge and neoforge and paper and purpur and spigot?
RRDiscordBridge officially supports bukkit, fabric, forge, neoforge, paper, purpur, spigot for Minecraft 1.21.10, 1.21.9, 1.21.8. 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 RRDiscordBridge – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if RRDiscordBridge 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.
