"Your connection is not private"

[pj-pj-pj]

I can't open any of the sites I've deployed with Vercel because I keep getting a "connection is not private" error. I don't think I changed any settings, except for pushing my latest branch. But even my other sites that I haven't changed are showing the same issue, so I don't think it's related to my code changes.

What can I try to fix this?

Would adding a custom domain help?

I really need to get my site back up. Thank you!

This error usually happens because the website’s security certificate (SSL) is invalid or has expired.
The browser cannot verify that the site is secure, so it blocks access to protect users.
If you're using Vercel, it might be a temporary issue on their side, or the SSL certificate hasn't been reissued properly after deployment.

--How to fix the "Your connection is not private" error on Vercel:--

1. Open the website in incognito mode or use your phone with mobile data (4G) to check if it loads.

2. Go to Vercel → Dashboard → select your project → click “Redeploy” (to refresh the SSL certificate).

3. If you're using a custom domain, check the “Domains” section to see if there are any warnings.

4. If it still doesn’t work, wait a bit and try again, as Vercel might be undergoing maintenance.
