Based on the video, the "Sign in with Google" flow is failing to establish a valid session. This is usually caused by one of three things, Corrupted Browser Cookies: Your browser might be holding onto a "stale" or expired session cookie that conflicts with the new login attempt. Third-Party Cookie Blocking: Modern privacy settings (or Brave/Safari "Shields") often block the specific cookies needed to "talk" between Google’s login servers and the Vapi dashboard. Cross-Site Tracking Prevention: Some browser extensions (like uBlock Origin or Privacy Badger) can accidentally kill the redirect script that finishes the login process. Here is what i think you can do, Try opening a new Incognito or Private window and logging in there. If it works: The issue is definitely your browser's cache or cookies. If it doesn't: The issue might be on the service side (Vapi) or a deeper network restriction. Clear Site-Specific Data You don't need to clear your entire browser history. You can target just this site: While on the login page, click the Lock icon in the address bar. Select Cookies and site data (or "Site settings"). Click Manage on-device site data and delete everything listed for vapi.ai. Refresh and try again. Disable Ad-Blockers/Shields If you are using Brave or have an extension like uBlock Origin, disable it specifically for the Vapi login page. These tools often block the "redirect" pop-up that tells the site you've successfully authenticated. Check Browser Clock This sounds strange, but if your computer’s system time is off by even a few minutes, the security tokens (JWTs) used by Google and Vapi will be seen as "expired" the moment they are created, causing an immediate logout. Would you like me to walk you through how to check your browser's Console for specific error codes if the steps above don't work? It might reveal a specific "401 Unauthorized" or "CORS" error that could point to the exact culprit.
