but this program performed an operation which requires it.

Steps to reproduce the behavior:

  1. Execute script "Maka-a-server" making variable server_type='forge'.
  2. Execute script "Automatically accept the EULA".
  3. Execute script "Run a Minecraft Server on Google Colab!"
  4. After connecting tunnel service, no matter which one, it always appears java error:
    java.net.preferIPv4Stack=true
    Found java version 17.0.1
    Exception in thread "main"
    java.awt.HeadlessException:
