Antigravity login error: “There was an unexpected issue setting up your account” bug. Then also not working for AI models

Thank you for bringing this to our attention. We have escalated the issue to our internal teams for a thorough investigation.

To ensure our engineering team can investigate and resolve these issues effectively, we highly recommend filing bug reports directly through the Antigravity in-app feedback tool. You can do this by navigating to the top-right corner of the interface, clicking the Feedback icon, and selecting Report Issue.

Not able to post feedback of bug report

For me on Windows, the issue has now resolved itself without any further action (I didn’t log out, but about 3–4 hours ago the model wasn’t responding to requests either)
On macOS, I used a mobile hotspot to log in five hours ago
Everything is working for now; I hope a server-side fix has been released

I’ve tried submitting bug report couple of times, typed in the explanation, added a screenshot but it just hangs on submitting indefinitely

Using a VPN resolved the issue quickly for me.
