SSL certificate authority invalid error on .vercel.app domains

Help

I’m experiencing SSL certificate errors across all my Vercel projects that use .vercel.app domains. This started happening a few hours ago and affects:

  • Multiple projects (university-client-theta.vercel.app, university-server-fawn.vercel.app, and others)
  • Multiple devices (different laptops and PCs)
  • All browsers

Current Behavior

I see the following error:

Error: NET::ERR_CERT_AUTHORITY_INVALID - “Your connection is not private”

What I’ve Tried

  • Redeploying projects
  • Removing and re-adding domains
  • Testing on different devices and networks
  • Changing DNS servers
  • Flushing DNS cache

Additional Context

Workaround: Using VPN allows me to access the sites, but without VPN, all .vercel.app domains show SSL errors.

Expected behavior: Sites should load normally with valid SSL certificates like they did yesterday.

Is this a known issue? Are others experiencing this? Any ETA on a fix?
