A few days ago I created a server on the Java Edition platform and played with my friends as usual and today I opened the server to continue playing. But I found that the server was not saying it was open. But it is loading, so I checked the command bar and found the server was open and able to play but it was loading state. So I thought this might be the server cache, so I was playing normally. But after a while, the server shut down while in the load state followed by an error state.
