Configure notification email address - stuck at domain verification

[Sandy L]

I'm following the steps listed in Configuring Jira Cloud to send emails on behalf of your domain set up a custom notification email address for Jira Service Desk. I've completed steps 1 through 3, and https://domain-check.atlassian.com shows "Success, domain properly set up!"

However, when I tried to set up the custom notification email, it throws the "DKIM validation failed for this domain" error.

I'm getting the same error as in the first question here, but a few hours have passed since I've set up the domain keys. Any clues?

Just tried again and it finally passed validation. It took about an hour since the DKIM were set up.

Edit: I tried changing the email address again (to another one in the same domain), and it's now showing the "Domain claim failed for this domain" error.
