About this Mod
ProximaTunnel

⚙️ How it works
- You can place the plugin file into the plugins folder on your server. In this case, it will work as a plugin and automatically add the server to your list when launched.
- Alternatively, you can place the same file into the mods folder on your client. In this mode, it will work as a mod. To allow your friends to join, you need to open your single-player world to LAN.
- Your friends can connect to proximamp.com using the Minecraft version supported by your server (or ViaVersion if installed).
- Once connected, open the menu.
- In the bottom-right corner, select “Локальные сервера” (command block icon).
- Choose your friend’s server from the list and join instantly.
Why use ProximaTunnel?
Hosting a server for friends is often tricky: opening ports, configuring routers, or downloading additional tools.
With ProximaTunnel, you just start your server, and your friends can join immediately.

- Start the server again – your setup is complete!

ProximaTunnel 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 (1.21.11). You can switch loaders with one click in the panel.
Is ProximaTunnel compatible with bukkit and fabric and forge and paper and purpur and spigot?
ProximaTunnel officially supports bukkit, fabric, forge, paper, purpur, spigot for Minecraft 1.21.11, 1.21.10, 1.21.9. 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 ProximaTunnel – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ProximaTunnel 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.
