Cloud JIRA and Confluence Authenticating failure

[Skip Sailors]

I have a Cloud JIRA and a Cloud Confluence.  When I am in a Confluence page I can insert a JIRA issue.  I can type the JIRA number and it makes a link as expected.  When I go back to the JIRA page, there is a link that says "Page" that goes back to the Confluence page, as expected.  By the link, where I expect the title of the Confluence page to appear, I see, instead, "Authenticate to see additional information..."

I obviously have some of the authentication configured, but am missing something.  I go to the Adminsitration | Applications | Application Links form.  There I see that the link to confluence system has a red "CONFIG ERROR" on its row.   I hit the pencil.  I see the Outgoing is OAuth and the Incoming is OAuth (impersonation)  The error message says that I have to make them both the same.  OK.

I select OAuth for both and hit save.  I refresh the page and the incoming reverts to OAuth (Impersonation).  I select OAuth (Impersonation) for both, and Save, and refresh, and the outgoing reverts to OAuth.  I am now confused.  Can you help unconfuse me?  What do I do to make the protocols consistent?

Hi, Skip,

We would need some further information, together with some tests that would need to be made on your instance, in order to troubleshoot.

Because of that, we kindly ask you to raise a ticket with us at Support: https://support.atlassian.com/contact.

Thanks!

I would try deleting the application link on both sides and recreating it.
