Environment
Both JIRA and Confluence were migrated from Cloud and now running on servers.
Diagnostic Steps
Application link was not able to connect even after proxy and SSL was bypassed.
Regardless if Confluence and JIRA are running on the same or different server.
Cause
This issue wasn't caused by the network as shown in the error message. There might be some old OAuth token in the database used in the Cloud instance that's not longer used in servers. These OAuth token needs to be removed and recreated.
Solution
Resolution
Always back up your data before making any database modifications. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
Delete any existing application link from both JIRA and Confluence.
Shut down both applications.
View the OAuth Tokens that exist in the database, by running the following query in your Confluence database:
1SELECT * from BANDANA where BANDANAKEY LIKE '%oauth%';Remove the old OAuth Token by running the following query in your Confluence database :
1DELETE from BANDANA where BANDANAKEY LIKE '%oauth%';Start up both applications and recreate the application link.
