Azure DevOps Services: GitHub Connection Issue — Integration Fails Starting September 7, 2026

Harsh Bhavsar 0

Problem description

I am experiencing an issue with connecting an Azure DevOps Services project to GitHub Enterprise Cloud. The integration was not successful ever. The support case mentions an error occurring during the setup, but no specific error message or code has been provided in the communication. I am seeking guidance on diagnosing and resolving this connection problem.

Environment

Azure DevOps Services; Azure cloud; Project-to-GitHub integration with GitHub Enterprise Cloud; no specific resource names, repository names, tenant details, or other identifiers provided.

What I've already tried

The initial agent reply did not include diagnostic details. Subsequent communications did not specify troubleshooting steps taken. The case references common checks such as authentication, token validity, browser cache, MFA, SSO behavior, repository permissions, and reconnecting the integration, but it is unclear which of these were actually attempted or what the outcomes were.

Current status

Currently, the connection failure persists with no detailed error message or specific findings. I am requesting assistance to identify the root cause, such as authentication or permission issues, and guidance on steps to resolve the integration failure.

Hello @Harsh Bhavsar

Since this connection used to work but started failing around September 7, first determine which GitHub connection type is failing before taking further action.

If this is an Azure Pipelines connection, go to:

Azure DevOps > Project settings > Service connections

Check the GitHub connection to see whether it uses the Azure Pipelines GitHub App, OAuth, or a Personal Access Token (PAT); Microsoft provides different troubleshooting procedures based on the authentication type.

When setting up a connection with a GitHub App, you should go to the GitHub organization under Settings > GitHub Apps/Installed GitHub Apps and verify that Azure Pipelines is still installed and authorized for the repository in question. If repository access has changed, the app may still be installed but will no longer have access to that specific repository.

When using OAuth or a Personal Access Token, verify that the authorization/token is still valid and has the required repository permissions. Microsoft states that GitHub connections based on a Personal Access Token need the relevant scopes, such as repo, user, and admin:repo_hook, depending on the situation.

Also check the affected GitHub repository under:

Settings > Webhooks

For Azure Pipelines integrations that use OAuth or a PAT, verify that the expected webhooks are still there and check Recent Deliveries for any failed requests, since a failed delivery will include the HTTP response or error that the Azure DevOps UI isn't showing.

It's important to clarify one term: you've referred to GitHub Enterprise Cloud. Could you confirm whether this is the standard GitHub Enterprise Cloud available on github.com or an Enterprise Cloud organization using a dedicated *.ghe.com environment? Don't use the connection instructions for Azure DevOps GitHub Enterprise Server unless you actually have GitHub Enterprise Server; that requires a different integration.

Since the failure is said to have begun on a particular date, also check the Azure DevOps and GitHub service status/history pages to identify the exact time period when the failure occurred. However, don't conclude this is a Microsoft-side outage unless you see an error message or evidence of a service incident.

Could you provide:

whether this is an Azure Pipelines or Azure Boards GitHub connection
the connection/authentication type (GitHub App, OAuth, or PAT)
the exact error message displayed when the connection fails
whether the Azure Pipelines GitHub App still has access to the affected repository
whether this affects all repositories or only one
When using OAuth or a Personal Access Token, does GitHub's webhook display an HTTP error in its Recent Deliveries?

Please remove the organization and repository names, as well as the tokens and any other identifying information.

With those details, we can distinguish between an expired or revoked authorization, a change to the GitHub App's access to a repository, a webhook problem, and a service-side issue.
