Hmm so oddly enough this works fine for me:

  $ curl -v https://vivianvoss.net/ 2>&1 | tail -3
        <script src="/assets/scripts/perf.js"></script>
    </body>
    </html>
And the logs show it is going to the same address:

  * Established connection to vivianvoss.net (78.46.78.181 port 443) from 172.16.245.55 port 36208
Any chance you're a comcast xfinity customer? Searching for safebrowse.io shows that xfinity "advanced security" does this whole redirect to safebrowse.io.

Unrelated, but the site also returns an AAAA record for an ipv6 address that does not work. So they've misconfigured their server in that regard.

  $ drill vivianvoss.net AAAA  @1.1.1.1
  [...]
  vivianvoss.net. 3600 IN AAAA 2a01:4f8:120:34ad::1
  [...]
  
  $ curl --header 'Host: vivianvoss.net' 'https://[2a01:4f8:120:34ad::1]:443'
  <hangs forever>

  $ curl https://ipv6.google.com
  <works immediately>

Some further digging ...

-------

$ dig vivianvoss.net A +short @8.8.8.8

78.46.78.181

$ curl -v4 https://vivianvoss.net/ 2>&1 | grep -E "Connected|error"

* Connected to vivianvoss.net (78.46.78.181) port 443

* OpenSSL/3.0.13: error:0A00010B:SSL routines::wrong version number

$ curl -s https://ipinfo.io | grep org

"org": "AS7922 Comcast Cable Communications, LLC",

Same IP you're hitting, same port, but Comcast's xFi Advanced Security seems to be MITMing the connection before TLS completes.

I hate Comcast so much ...
