Hey there!
If you are having issues with the dashboard, try logging out, turning off your browser and reopening and try to restart it.
The server will hibernate after 5 minutes of in-activity on the server. This is so other users can enjoy there servers on minehut.
When joining the game and you are met with that, its usually because you are not on a premium Minecraft account (cracked). Make sure you are on a monjang account. Minehut is not a cracked server.
I really hope this can help you.
Good luck!
