I've been getting this error message since yesterday when I try to connect my github account to Google Cloud Build. I tried multiple google cloud accounts, github accounts, and browsers. All got the same error. Any one faced the same and figured out how to fix it?

Be careful!

The redirect_uri is not associated with this application.

The application might be misconfigured or could be trying to redirect you to a website you weren't expecting.

Hi @eric-wong-hk,

Welcome to Google Cloud Community! 

The "redirect_uri is not associated with this application" error specifically relates to the OAuth 2.0 flow, which is a common authentication mechanism. Connecting GitHub to Google Cloud Build does use OAuth for authentication and authorization. A key part of OAuth is the redirect_uri, which tells GitHub where to send you back to Cloud Build after you've authorized the connection. The redirect_uri are supported, check if you are missing this part.

Additionally, the GitHub issue thread here contains additional useful information.

If you need further assistance and any questions, please reach out to our Google Cloud Support team.
