i setup and aname on my dns with drive.mailcowserver.com and then ran the nextcloud helper script. I added “drive.*” to additional san. I can now get to the next cloud login page and have an account.
HOWEVER… now all my “other” domains go to the nextcloud login page as well. the main fqdn of the server goes to the webmail portal as expected. all other domains go to drive.mailcowserver.com.
this is a by the book install. No deviations have been made from the install documentation. I am not running a proxy and i do not have the https re-direct enabled. I do have ipv6 disabled. I do have a good ssl cert on “drive.mailcowserver.com”
