On March 2, 2022, all OAuth integrations between Git Integration for Jira and Azure DevOps and VSTS were interrupted. Our investigation found that Microsoft OAuth apps’ client secrets expire after 5 years. This limitation has a single workaround and that is for all customers to reconnect. We apologize for this inconvenience and interruption in service. Below are steps to reconnect.
Workaround: Reconnecting Azure DevOps and VSTS OAuth
Jira administrator permissions
Azure DevOps / VSTS account or service account.
Visit the Manage Git repositories screen in the Git Integration for Jira app
Click on the integration name
Click on Reconnect
Login to Azure DevOps / VSTS with the account you wish to associate with Git Integration for Jira.
