Migration Assistant reports Can't communicate with server

Within an administrative session with our Confluence Server instance, I started the Migration Assistant. When the Assistant launches, it throws a window reporting,

"We can't communicate with your server

We're having trouble communicating with your server instance. Please try again. If this doesn't fix the issue, contact support for help."

I restarted my browser, logged in again (via Okta, I'll tell you in case that makes a difference), started the Migration Assistant again. Still no joy.

Cloud SEN: SEN-31662493 (trial)

Thank you,

Hi @Brian Moore

Welcome to the Atlassian Community. 

We understand that you are facing any issue with Connectivity when attempting to use the migration assistance. Could you please check Step #9 in the below Confluence pre-migration checklist document and make sure all Atlassian domains or endpoints you need to allow in your firewall are done. 

Let us know if the above information helps.
