Issue Summary

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Have at least one time executed the review of the domains and the user assessment
2. Enable the DF com.atlassian.jira.migration.skip.users.preflightcheck to skip the user pre-flight check
3. Go back to the review of the domain and click on the Assess again button

Expected Results

The scanning of the email domains will be executed properly resulting in a list of domains.

Actual Results

The scanning of the email domains finishes in a few seconds with the message "No domains found".

There are no exceptions, errors, or warnings logged in the atlassian-jira.log or atlassian-jira-migration.log files.

Workaround

Avoid using the DF (preferable)

Disable the DF com.atlassian.jira.migration.skip.users.preflightcheck.

Reset the email validation

Execute the REST API on the browser:

• BASE_URL/rest/migration/latest/debug/email/remove-all-domain-rules

This will remove all the domains previously listed from the list.

To trust them all in bulk, execute the following REST API endpoint on the browser:

• BASE_URL/rest/migration/latest/debug/email/trust-all-domains

After that, the user can go over the list and untrust any domains you might not want to get approved.
