# Connection lost could not connect to a default or fallback server

##### What does this error mean?

Your Minecraft server client cannot connect to a sub-server on a bungee server.

<p class="callout warning">If the issue does not resolve after 5 minutes we recommend you contact our support team **[here](https://you.aquatis.host/submitticket.php)** as soon as possible!</p>

##### What causes this error?  


This happens when the sub-server is either offline or it has crashed.

##### What should I do?  


- Try to restart the server and see if you're able to connect.
- Try to join the server directly without using the bungee server.
- Double check and ensure the config is correct.
