I’m facing a recurring issue while using Google AI Studio (Gemini Studio). Whenever I try to open my project in any browser other than the one I originally used for development, it shows this error message:
“Failed to load the app. Try reloading it.”
The app only loads in the browser where I first created or edited it. On any other browser, device, or after clearing cache, it fails to open and keeps showing this same error.
This happens both for projects integrated with Supabase and also for plain apps without any external integrations, so it doesn’t seem related to my code. Other developers are also reporting the same issue on the forum, which suggests it might be a Gemini Studio environment or session bug.
Could you please confirm if this is a known issue or if there’s a temporary fix available?
Thank you for looking into this — it’s affecting project access and sharing across browsers.
Também estou enfrentando esse problema há mais de 5 dias. Há alguma previsão para correção do erro ou uma possível solução temporária? Estou utilizando o preview em ambiente local (localhost).
I had this problem for 5 days. To resolve it, I connected my computer to the wifi hotspot on my phone. Using a different network seems to be the solution which suggests a network config issue is at play, as some other person posted and resolved through using a VPN.
Yup, same issues and still persisted. Clear cache, logged-out, refresh, auto fix and even try new project and no luck. It works for few hours earlier, but stopped working again
Just fixed this after it has been an issue for over a week.
My networking gear from my ISP (AT&T) was blocking the URL aistudiocdn as a website that “poses a spam risk”. It said it poses a suspicious behavior you should avoid.
Either Google needs to work with the ISPs or maybe just change the name of the CDN to get it unflagged?
Go check that your networking gear hasn’t blocked this - AT&T just proactively does it and it was in the list in their companion mobile app for their service.
The AI security checker blocking the AI builder tool. It’s a fun future ahead of us with the AI’s flagging each other.
This is it. I went to my SmartHome manager and had a notification that it was blocked as well. I allowed access and it immediately worked. Good work ai_cowboy
Thank you @all for sharing your fixes and helping the community.
For any one new who are still facing the issue, here is the summary of solutions posted by the community:
This issue could be with network security settings, firewalls, or ad-blockers that are incorrectly blocking a critical Google domain: aistudiocdn.
Here is a step-by-step guide to resolve this issue, based on successful fixes from fellow community members.
Whitelist the aistudiocdn Domain:
Your Internet Service Provider (ISP) or home router may be automatically blocking this domain as a “spam” or “malware” threat. You need to manually allow it.
Check Your ISP/Router App: Open your ISP’s management app (e.g., AT&T users should check the AT&T Smart Home Manager app) or log into your router’s admin panel.
Look for Security Alerts: Navigate to the security, firewall, or advanced settings section. Look for a list of “blocked threats” or security notifications.
Find and Allow aistudiocdn: You should see aistudiocdn listed as a blocked domain. Select it and choose the option to “Allow Access,” “Unblock,” or “Whitelist.”
Reload AI Studio: Once you have allowed the domain, refresh your AI Studio page. It should now load correctly.
Optional Steps: Some users found disabling Your Ad-Blocker and clearing browser cache to be helpful as well.
Please try the above steps and let us know if you are still facing the issue.
Watch this video, it solve the problem magically. Basically we need to remove the script tag and its components from index.html and somehow the app starts working, magically.
