No clues in journalctl -u mailinabox
, just normal startup and SSL provisioning stuff.
Anyway I have identified 2 folders that had bad permissions resulting in /admin
not being able to function, my fix was to chmod them again
/usr/local/lib/mailinabox/vendor
0664 to files, 0775 to folders/home/user-data
0664 to files, 0775 to folders (before requesting for SSL certs)
