Same issue. I made a video documenting it, as well: https://www.youtube.com/watch?v=j31w97a3fxA
A Google search for "Minehut server not starting" has the entire first page of results filled with practically identical subject lines; so many servers are broken that the news is dominating the internet. Yet there's no word from Minehut. I have an open support ticket (on another issue, mind you) and was in email contact with them until the middle of last week, when all communications abruptly stopped. They're not responding to emails, and they're not resolving the broken server issues via their Discord server.
Apparently Minehut is dying, and their tech support have abandoned ship. Time to look for another hosting solution, apparently. Hope you all have backed up your worlds already.
