This can happen due to multiple reasons and will be specified in this guide.
The first step is to go to Scalacube.com and log in to your account.
Click on "Servers" and then "Manage server".
Click on "Manage" again.
The error can be seen in the server console after selecting your server and going to "Console".
Reason 1: You uploaded a custom .jar and the server is not reading it. It can be that the .jar file itself is corrupted and might require re-uploading.
Reason 2: The .jar file was not uploaded into the correct directory. Go back and make sure that it has been placed in the same folder the old .jar file was in.
Reason 3: Make sure the .jar file is renamed as to what the previous .jar file was. In this case the file should be named "server.jar".
After making sure that all these criterias are met and the .jar is still not operating correctly, you can contact our support for further information.
