There are many places where useful logs reside. This details all those places, and the easiest way to get a hold of them.
To check if there are relevant logs open up the developer console. The shortcut is probably COMMAND+ALT+I on MacOS, or CTRL+ALT+I on Linux and Windows. Click the console tab and copy out any errors or logging that you think is relevant.
The easiest way is to use medic-logs, a tool that comes with medic-conf:
medic-logs anInstance gardener
See medic-logs documentation for more details.
This will download logs to your current directory. You will need to look through these logs to work out what is relevant.
