Summary

Application link between Jira Software and Jira Service Management not working with an OAuth mismatch error.
We have to use regular OAuth and not Oauth with impersonation for some time until our usernames match again, and when trying to set the Application link between Jira Software and Jira Service Management, we receive an OAuth Misconfig error.

Environment

Jira Software 8.5.8

JSD 4.5.8

Diagnosis

When trying to link using OAuth, we can see this error in the UI:

OAuth mismatch
The local incoming connection uses OAuth, however “JSD” uses OAuth with impersonation
The local outgoing connection uses OAuth, however “JSD” uses OAuth with impersonation

On atlassian-jira.log, we can see the following error on both instances:

2020-11-06 13:44:21,575-0600 http-nio-8080-exec-15 WARN diegovb 704x43960x2 u0t60i 10.230.56.90 /rest/applinks/3.0/status/d54hg145-2ee3-3325-ba88-d3253f535gv [c.a.a.i.migration.remote.TryWithCredentials] You do not have an authorized access token for the remote resource.


Cause

Jira Service Management requires to use OAuth with impersonation

Solution

Create an Application link between Jira Software and Jira Service Management using OAuth with Impersonation.
