Summary
While accessing a Jira issue from Bitbucket Server UI, seeing the "Connection lost with Jira Cloud" message
Environment
- Bitbucket Server/Datacenter
- Jira Cloud
Diagnosis
You'll see the following message when you click on a Jira issue key on the Bitbucket UI:
The below can be seen from the Bitbucket application logs:
WARN [http-nio-7990-exec-107] username @1TB8ENDx45XXXXXX 16zxkr0 XX.XXX.X.XXX "GET /rest/jira-integration/latest/issues HTTP/1.0" c.a.i.i.jira.DefaultJiraService Problem communicating with Jira instance 'Jira CLOUD' at '<Jira-Cloud-URL>'. Error: No content to map to Object due to end of inputBitbucket server and Jira Cloud are connected via Application links as mentioned on this page: Link Bitbucket with Jira and the application link is using OAuth.
Cause
This issue is caused by the bug on the Jira side JSWSERVER-14908. This bug reports a similar error when the app link has been established between Jira and Bitbucket and OAuth user impersonation has been disabled.
Solution
Delete and recreate the Application Link. You may need to delete the link separately on each side before recreating it. After recreating the application link, the users might have to authorize themselves on Jira and Bitbucket.
