Hello my friend. I am a user on this platform. I do not speak for or behalf of the CubeCoders team.
Do you have the crash log? I used the Minecraft module with Virtualization using docker, I had some errors as well. Although I didn’t mind it and ran it without Virtualization.
I went through some errors regarding the Forge installation as well. It was because the server jar file wasn’t chosen by default, although I read on one of the changelogs that the CubeCoders team has fixed it.
Since you mentioned using Forge, I assume you have a modded server. Which means a lot of errors as well. Double check the installed mods for any incompatibility issues.
