Re: Can't connect to torproject.org

I feel silly for not being able to figure this out.

I can't connect to torproject.org via either Firefox or Chromium. The
browsers object that HSTS is in place and they don't recognize the
site's certificate (SEC_ERROR_UNKNOWN_ISSUER). There's no opportunity
offered to add an exception.

I've seen these threads:

https://support.mozilla.org/en-US/questions/1201504
https://superuser.com/questions/1066863/how-can-i-add-a-certificate-exception-for-an-hsts-protected-site-in-firefox
https://support.mozilla.org/en-US/questions/942924

But I don't see any good suggestions for fixing this in my case. I have
a pretty standard Debian installation, with standard certificates
installed, and no customization to my local certificate infrastructure.
I'm connecting via Verizon FioS, with no proxy in use (on my end, at
least).

There seems to be to issues:

- The certificate issuer is invalid
- Since the site uses HSTS[0], the browser does not allow the user to override the certificate problem.

HSTS doesn't really seem to be problem. It just tells the browser that https is to be used at all times. If there's a certificate error, that means that TLS is being used.

The real question is then why is the issuer considered invalid. I can access the site normally and it uses a Let's Encrypt certificate, which should be trusted, and should be used by many other sites.

What happens when you try to access https://letsencrypt.org/, which is signed by the same CA?
