Issue Summary

• New application link creation fails on the Confluence side when connection to Jira Cloud.
• Existing application links work as expected.

Steps to Reproduce

1. In Confluence Cloud, attempt to create a new OAuth 1.0 or 2.0 application link to Jira.
2. Start the same process on the Jira side, and copy/paste the "App client ID" and "App client secret" to complete the setup.
3. Notice that the application link is completed on the Jira side.
4. On the Confluence side, the link returns a "Network Error", with this response.

   • We couldn't connect to Jira at https://api.atlassian.com/ex/jira/<CLOUD-ID>. This might have been caused by a network error or another configuration error.
     
     java.lang.RuntimeException: Failed to retrieve client credential access token

Expected Results

• Application link should be set up without any errors on both apps.

Actual Results

• While Jira is able to connect to Confluence, the setup fails on the Confluence side and returns a "Network Error"

Workaround

• Currently there is no known workaround for this behavior. A workaround will be added here when available
