Hello, so I just installed AMP and I have deleted and created many instances but to no avail. I checked the console and it seems like everything got installed correctly but this error keeps popping up in the panel:

Unable to start server.

The update manager reported a successful update, but ./Minecraft/minecraft_server.jar is missing.

The console output here is this after installing FTB University 1.16 into the instance and running : https://www.toptal.com/developers/hastebin/imezacehap.yaml

Since I'm new to AMP, I do not know where the Minecraft server folder is located even using Bitvise SSH Client. Is there any solutions to this problem?

EDIT: Totally forgot to select the jar file in the settings of the instance, and I chose Forge jar for this case.
