Problem description

By default, we automatically allow Atlassian-supported domains to access apps in your organization. You can add the domains you trust or block Atlassian-supported domains.

The same is true for Atlassian MCP connections, as we provide a screen on Atlassian AdminHubs for them to add their domains as required. 

Suggested solution

Increase the number of supported domains, allowing administrators more flexibility.

Workaround

Remove one of the previous domains from the list so you can add more, since they shouldn't be required to persist in the configuration after authorization.
