For help regarding Aternos, we recommend you to visit our support center.

    If your getting the error message “Failed to synchronic registry data from server” then check the following:

    1)The client side forge/fabric version should match the server side forge/fabric version

    2)The mods installed on your Minecraft client (your PC) including the versions need to match the mods installed on your server (Exceptions like sodium and other client side mods)

    3)If the forge/fabric version and the mods installed match then try deleting deleting the config folder which is located in the minecraft installation path (enter %appdata%/.minecraft in the file explorer )

    3)If none of the steps above work then share your client log and server log.


    How to 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
