@Shaun-Snapp said in Add an A record manually for the domain:
"Add an A record manually for www.abc.com to this Cloudron's public IP"
I purchased the domain around 1/2 hour before trying to change an app to that domain. This is the error I received when the app failed to propagate.
That message is saying that you have to add the A record manually in your domain provider (not in Cloudron). Cloudron cannot add/remove DNS entries for the domain because it's "manual" mode and thus has no programmatic access to your DNS.
The place where you purchased your domain most likely has a Domain/DNS control panel where you can add/remove DNS entries.
