GitHub pushes not triggering deployments + tokens return "User not found"

My GitHub pushes to my repo (wingroupinversiones/plataforma-bim) have stopped triggering new deployments on my project "plataforma-bim-49hl" since around 5+ hours ago.

What I've confirmed so far:

The GitHub App integration still has repository access granted (confirmed in github.com/settings/installations)
The connected Git repository in Project Settings → Git is correct and shows no disconnection
There's only one duplicate project in my account with no domain/no deployment, ruling out a "wrong project" issue
I tried creating Personal Access Tokens (2 different ones, generated fresh from Account Settings → Tokens) to deploy via CLI as a workaround, but both return "User not found" when calling curl https://api.vercel.com/v2/user, even though I'm logged into the dashboard normally with the same account
status.vercel.com shows all systems operational
The last successful deployment was several hours ago; every commit since then simply doesn't appear in the Deployments list at all — not even as "Building" or "Error"

I'm on the Hobby plan, so I don't have access to a dedicated support ticket for this. Has anyone experienced something similar, or does anyone know what else I should check?

It sounds like a metadata issue. Make sure the use info on the commits matches your GitHub account info

Preview deployments stuck in UNKNOWN/BLOCKED state before build starts

Title: Preview deployments stuck in UNKNOWN/BLOCKED state before build starts Body: Hello, I am experiencing an issue with my Vercel project where all new...

Update — the issue persists, and I've ruled out several possible causes:

Confirmed the latest commit (1cffac8) reached GitHub successfully on main (git log --oneline origin/main confirms it). Fully disconnected and reconnected the Git repository integration in Project Settings → Git (wingroupinversiones/plataforma-bim → plataforma-bim-49hl) — reconnection succeeded ("Connected just now"), all events (deployment_status, repository_dispatch) are enabled. Pushed a fresh empty test commit (git commit --allow-empty -m "trigger deploy test") specifically to trigger a new deployment after reconnecting. Result: no new deployment appears at all in the Deployments list — not Building, not Error, not even a failed attempt. It's as if the push event never reaches Vercel. Ruled out billing/account issues: no payment problems, no restrictions visible under Account → Billing or Account → Overview. The GitHub App installation for Vercel shows the repository correctly authorized under "Repository access."

This has now been going on for over 24 hours across multiple commits. Since I'm on the Hobby plan I don't have access to a support ticket — has anyone on staff seen this specific pattern (repo connected + authorized, but zero deployment activity on push)? Happy to provide the project ID or any other diagnostic info that would help.
