Once CNAME entered and confirmed for community.mydomain.org.au
Current board url is mydomain.peerboard.com
You have requested to change the board domain to 'community.mydomain.org.au'
Can you please confirm that your new url works and you have access to admin panel from there?
Hitting Confirm here will enable a hard redirect from the old address to your new one.
I can generate a sign in link at community.mydomain.org.au
When I follow the sign in link it redirects to mydomain.peerboard.com
i.e. I can't access the new url for anything other than generating a link
