traccar 6.2 impossibile export report

hello,

please note that in Traccar 6.2 it is impossible to export the report (I tried daily summary). It gives an unreachable site error.
While if I try to send it by e-mail, the server crashes

What operating system and database engine do you use?

I use ubuntu server 24.04 x64 and the default h2 database.
I used to use 6.0 before and it worked fine

What's the error in the logs?

Looks like the service was stopped.

yes, this interrupts itself when I press the 'export' button in reports

I don't think that's possible. Check systemd logs.

Below are the logs while I had the problem and of the following restart. I do not see any significant errors.
web side I have a CONNECTION_REFUSED error

And systemd logs?

hello,

I reinstalled traccar from scratch and it now works.
Thanks for your help, I don't know what happened
