Please try to connect to your server with the Dyn IP. This article explains what that is and how to use it: https://support.aternos.org/hc/articles/360026805072

Try restarting your Minecraft. If this won't work share your client log

Share your client log:
1. open your minecraft installation path (enter %appdata%/.minecraft in the file explorer )
2. open the logs folder
3. open the "latest" or "latest.log" file with a text editor
4. copy and paste the content of the file to https://mclo.gs/
5. send the link here
