I had the same error and this is what fixed it for me:
My AT&T home router’s overly eager guardian decided that aistudiocdn was a known spam source and blocked access. Fortunatley, through it’s app I was able to unblock (re-enable) access to aistudiocdn and all was well again.
I thinks this makes sense why switching browsers that might use a vpn or otherwise obscure the access may have fixed the problem for others. If this was what you had to do to fix it maybe double check that your router or other internet safe guard blockers aren’t blocking aistudiocdn
This is the clue - my phone’s lock screen when I finally reached for it:
Podría ser la configuración de Facturación, si no tienes agregada una, registrala a tu cuenta y proyecto que estes trabajando. Si ya tenías configurada la Facturación y esta en orden, intenta reestableciendo tu Api Key en Google Studio.
Salvo mejor criterio parecería que es un error al momento de llamar a las Api de Gemini.
Same issue has brought me here. Has Google looked at the recent changes that may be contributing to this? Chat retention is new and in my experience with other AI tools - there is a total line limit in chat history that hampers AI performance. Yes retention may sound nice - but I find it better to version, save, copy and work from a bible or canon with fresh chats for better performance. They don’t even allow us to personalize that choice. I’d rather use my cache to build new as opposed to having it ‘remember’ my chat history. Also all updating code snippets are newly rendered as opened and need to be manually closed - this eats up value lines of chat history on top of remembering total chat history. We may all be experiencing cascading impacts of these changes Google pushed, it may just take us each a different amount of time to hit the max tolerances based on how much we are updating any individual app.
I have the same issue. I have disabled all browser extensions and turned off my VPN, but still no preview. Lovable and Replit do not seem to have this issue.
I’m experiencing the same issue described here.
All my previously created AI Studio apps suddenly stopped rendering and show only a blank screen in both the Builder Preview and the deployed Cloud Run version.
Interestingly, any new app I create today works normally.
In my tests:
– Chrome, Edge and Firefox all show a blank screen
– Safari works correctly
– mobile Chrome also works
– multiple devices and networks show the same behavior
I’m curious if others here see the same pattern:
Does Safari still load your older AI Studio apps while Chrome-based browsers fail?
This happened without any code changes, so it looks like something affecting existing project runtimes rather than new ones.
I deactivate my ad-block on this site, chage dsn for Public DNS (8.8.8.8 i 8.8.4.4) delete history and chace form last 7 days and i have a still the same problem - no prewiev at all. anyone to fix it?
If the preview of your Google AI Studio app appears broken or blank, try this: initially, connect your laptop to a mobile hotspot instead of Wi‑Fi and then reload AI Studio.
If it functions on the hotspot but not on your home Wi‑Fi, the problem lies with your router or ISP blocking certain CDNs (such as the domains AI Studio and Tailwind use), rather than your code.
In this situation, you can either continue using the hotspot while working in AI Studio or access your router settings and deactivate any web-filtering/parental-control features to unblock specific domains.
