@sahsanu can you move the posts/comments from this onwards to here, as it relates to this thread.
I found out why it was not working. Unable to add **panel.domain** as **domain** belongs to a different user
I had to change the config under settings > security > policies > Enforce subdomain ownership (change to NO) and then recreate it. It worked. The CLI gives the correct reason, but the UI pop-ups do not. Maybe this can be altered in the code to allow users to know the error reason in an accurate manner?
Update 09.03: Thanks. The root email error has vanished now.
I have this forum to thank a lot. I would not have taken the bold step forward to host over my own and not via cPanel if it was not for this place. Really appreciate everything done here.
I will look into how to donate via bank and not paypal. It is one of the devil incarnation.
