Glad to hear that you managed to work around your issue, although the firstboot inithooks should have added the domain you selected at firstboot to the "trusted domains"?! So if that didn't work, then perhaps there is a bug?!
Another possibility is that comes to mind is that the recent issue with MariaDB caused the issue? Although TBH, I'm not sure that's it as you state that Adminer (and Nextcloud) were working, so that seems unlikely?!
