Steps to Reproduce:
1. Deploy the Gradio app with authentication enabled to Cloud Run.
2. Access the app via the provided URL.
3. Observe that the loading indicator is restored indefinitely and the sign-in page never appears.

Expected Behavior:
The app should transition from the loading state to the authentication page, allowing users to sign in.

Actual Behavior:
The app remains stuck on the loading screen and never reaches the sign-in page.

Environment:
• Gradio Version: 5.15.0
• Deployment Platform: GCP Cloud Run
• Date Observed: February 2025

Additional Context:
• The issue is new to this version and was not present in previous releases.
• No related errors appear in the Cloud Run logs.

Hi @ferdinandl007 - if you revert to an older version of gradio does the app load properly?

[freddyaboulton]

Nvm can reproduce even without Cloud Run

Yeah, it works when I revert back to an older version
