Hello.
According to this page: Available regions for Google AI Studio and Gemini API | Google AI for Developers Serbia is a supported region and I haven’t had any problem accessing AIStudio just yesterday.
But today when I visit AIStudio page I get redirected to the available regions page, and my API requests are failing with “Region not supported” error.
Is Serbia no longer supported?
Same country, same problem. Tried verifying my age just to be sure but still no luck.
hooray the restrictions has been lifted, i can access the ai studio now 
Hi,
I have the same in issue. Belgium is in the availabe region but it doesn’t work for me.
I’m in Belgium, and Google AI Studio is currently working for me.
I’m using the Gemini 3 Pro Preview model, and I am logged in with my Gmail account.
