504 Gateway Time-out

[markus-96]

I tried this two times.

When I ran vagrant up the first time, everything seams to work properly. Then I try to log in via https://192.168.56.5/admin everything works fine. But after about one minute or so, I get a gateway time-out for every single request to 192.168.56.5. In the logs of nginx there is nothing, and no single error is listed when I run systemctl status nginx.service.

Since I have no idea where the failure comes from, I can not provide any additional information like an error log. If you could tell me where I have to look I could provide one.
