So basically i made a new server but i wanted it to be on 1.15.2 so obviously i changed the version of the server into 1.15.2, then it told me that the version wont change untill i restart the server so i did restart the server but now the server just says "starting" for a few minutes after i try to turn it on then it changes to "offline" i even tried using the /join in the minehut server but that wont work too! Anybody know what's wrong?
