Network Protocol Error

image.png

“Network protocol error” often happens when the version of Minecraft you’re using isn’t matching up with the version the server is running. It might also show up if the server or your connection has issues—like an incorrect IP address, firewall settings blocking your connection, or even a plugin error. Here are a few things you can try:
 • Double-check that your Minecraft client has the exact same version as your server. Example: the server is on 1.20, for example, make sure you’re launching Minecraft 1.20.
• Confirm you’re using the right IP and port. 
• Make sure your server plugins or mods are updated and support the game version you want to play on.

Server not starting properly

Is your server not starting properly? Here are some possible fixes and steps to find the issue.
  1. Check the Console: Look in your Control Panel’s console (our custom panel) for any error messages that appear right before the server goes offline.
  1. Review Your Plugins/Mods: If you recently added a plugin or mod, try temporarily removing it. Sometimes outdated or incompatible plugins cause the server to crash.
  1. Check Server Settings: Make sure your server is on a compatible version. If it’s a modded server, you’ll want to ensure the mods match the server’s version.
  1. Monitor Resource Usage: If your server has a lot of players or mods, it might need a higher plan to give it enough CPU power.
If this didn't help please open a ticket at Alien Universe's Discord Server, under technical.
