This article explains why a redirect loop occurs when a user tries to log in. When this issue occurs, internal system logs for the impacted IP address indicate the following error.

State Error

This error occurs when the unique state parameter, used to secure the session, is lost or mismatched during the redirect. If an Application Login URI is configured, the system automatically redirects the user back to the login screen, resulting in a continuous loop.

• Application Login URI
• Browser Redirects

The state parameter is lost or mismatched during the redirect process, often due to browser extensions, security software, or aggressive cookie-blocking settings on the device. This can also be replicated by starting a login session in one browser and attempting to continue it in a different browser by pasting the URL.

To resolve the redirect loop and ensure the state parameter is maintained, perform the following steps:

1. Clear the browser cache and cookies.
2. Attempt to sign in using an Incognito or Private window.
3. Sign in from a different browser or a different device.
