I am stuck on the proverbial screen: 
I have waited over 15 min, tried canceling and reconnecting, but am unable to get past this screen, let alone connected. Our IT says there is nothing blocking this setup in Jira.
My only 'hunch' is if SSO has something to do with it? We use the Cloud solution for all our Atlassian tools, and I saw this was a blocker for the Server connections, but unsure about the Cloud version.
Seen a lot of other questions posted regarding this, but no resolutions.
