Question

mac os - terminal - opencode auth login - google - check quotas

Message: I'm running into a 403 error with my second account (df.nmixx@gmail.com) while fetching models from cloudcode-pa.googleapis.com.

The error asks me to verify the account via a Google sign-in link, but even after following the steps at that address, the verification isn't being recognized. My other account works fine, so it seems specific to this one. Has anyone encountered this "verification loop" or 403 error despite following the link? Any help would be appreciated!
