Looking for Logs of Dashboard/Manager/Middleware

Hi Devs,
after having a hard time restoring from a failed OS upgrade, I’m having another hard time trying to get back access to umbrel again. Altough bitcoin is fully synced and lnd is up to date, umbrel dashboard is still giving me the loading screen of death.
Now I’d like to see what exactly is the problem but after upgrade to 0.3.10 the logs for dashboard, manager and middleware have disappeared. They used to log into /var/log/syslog before. Now each service is split up into its own directory.
Please would you give me a hint where to look at? (Native installation onto Linux, no Umbrel OS used). Thanks!

Edit: Login doesn’t even respond to wrong passwords. That’s strange…
