Server starts then closes

It very much looks like either a manual shutdown or a timed shutdown, altho the time passed is not really long; It should have said it was online?

When I fully start the server, it closes.

I tried to download the world and test it out, use another browser, and update it to paper (since the world imported is from paper)

Here's the log:

Did This Happend one time or more times?
