Sign in to


starting today I cannot connect or login to pritunl when signing in with google. Our auth scheme is google + duo. I have checked and system account in GCP and it is still there. Key is not expired.

Flow is: pritunl opens SSO page. After selecting correct account the " Sign in to pritunl. com" page shows with info like " By continuing, Google will share your name, email address, language preference, and profile picture with pritunl. com. See’s Privacy Policy and Terms of Service."

When you click continue it throws error 400. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

How can I debug this?

The authentication errors would only be shown in the logs in the top right of the web console. I haven’t seen any other emails about issues with Google single sign-on.
