AI Studio app reports “Published / Ready” but custom ai.studio URL returns Not Found

Hi everyone,

I’m experiencing a publishing issue with a Google AI Studio Build Mode application.

App name: ScenePartner
AI Studio App ID: 15d1438e-d020-455c-a443-5e5514ad6f29

The app publishes successfully and AI Studio reports:

  • Status: Published / Ready

  • Custom URL assigned successfully

  • Cloud Run deployment is healthy

However, the assigned AI Studio URL returns a plain Not Found response:

https://scene-partner.ai.studio/

The original URL also behaved the same way:

https://scenepartner.ai.studio/

I have tried:

  • Republish from AI Studio

  • Changing the custom subdomain

  • Waiting for deployment completion

  • Testing in multiple browser tabs

  • Confirming that the underlying Cloud Run deployment works

The working Cloud Run URL is:

https://ais-dev-fyh5xq2u74btl7leyaofxh-429611920250.europe-west2.run.app/

This suggests the application build and Cloud Run deployment are healthy, but the *.ai.studio routing or project association is not resolving correctly.

The app was originally published while AI Studio was associated with the CityScope project, although I also created a separate scenepartner-studio project for the application. Could this be a stale custom URL binding or incorrect Cloud project association?

Could someone please help reassociate the AI Studio custom URL with the current deployment, or advise on the correct recovery process?

I would prefer not to unpublish the app unless necessary, since that may release the URL and create additional downtime.

Thanks!
