Failed to activate GitHub App installation after changing GitHub accounts #4701

Description of Bug

I am unable to connect my new GitHub account to Bolt.new after changing from my previous GitHub account.

Accounts and repository:

• Old GitHub account: sandeepgummadi01-ui
• New GitHub account: halyobookings-prog
• New repository: halyobookings-prog/halyo-global-development
• Project: HALYO

I previously had my HALYO project connected to my old GitHub account. I revoked the Bolt authorization from the old GitHub account and installed and configured the Bolt.new GitHub App on my new GitHub account.

However, Bolt consistently fails when attempting to authorize the new GitHub account.

Exact error:

OAuth provider Error: Failed to activate GitHub App installation

Steps to Reproduce

1. Open Bolt.new and sign in using my existing Bolt account.
2. Open the GitHub connection option.
3. Attempt to connect my new GitHub account (halyobookings-prog).
4. Authorize Bolt.new (by StackBlitz) through GitHub.
5. Install/configure the Bolt GitHub App and grant access to the new private repository.
6. Return to Bolt and complete the GitHub connection process.
7. The OAuth authorization window displays the following error:

OAuth provider Error: Failed to activate GitHub App installation.

8. Close the window and retry signing in. The same error persists.

Expected Behavior

Bolt.new should successfully authenticate my new GitHub account, activate the GitHub App installation, and allow me to connect and import my existing HALYO repository.

I should be able to use my new GitHub account without losing access to my existing Bolt project or its code.

Additional Context/Questions

I have already attempted the following troubleshooting steps:

• Revoked the previous Bolt authorization from my old GitHub account.
• Created a new GitHub account.
• Created a new private repository.
• Successfully imported my existing HALYO repository into the new GitHub account using GitHub Importer.
• Installed and configured the Bolt.new GitHub App on the new account.
• Granted repository access to the new private repository.
• Retried the connection using Chrome Incognito mode.
• Verified that the same error continues to occur.

Request:

Please investigate whether there is a stale GitHub OAuth association or GitHub App installation activation issue with my existing StackBlitz/Bolt account.

Could you help reset or repair the GitHub integration so I can connect my new GitHub account?

This is important because HALYO is an active production project, and I need to continue development without disrupting the existing project, code synchronization, or production website.

Thank you.
