Hi @it15.

After reviewing the screenshot of the log you provided, there appears to be a problem connecting to your H2 database. I'm guessing that after rebooting the server, you are running something that is using the same port as H2. This could explain why it works after a restart.

Here is a link to an H2 tutorial that may help you track down the cause of the problem.

Regards.
