If you are the owner of the server, you are able to go into the server's console via your Minehut dashboard.
From there you can type in /gamerule randomTickSpeed 3 on your server's console. (Or you can try this command in-game too.)
This should put the tick speed back to how it normally should be. We recommend restarting the server and trying again if you see that it hasn't worked the first time.
Please be sure not to set the Random Tick Speed above 3 to prevent lag and server crashes.
