Well I have been trying to connect with both Firefox and Vivaldi. I think it’s unlikely they are both bad.
So I did the following…
# nslookup> www.opensuse.org
Server: 208.67.222.222
Address: 208.67.222.222#53
Non-authoritative answer:
Name: www.opensuse.org
Address: 130.57.66.6
linux-dqd8:/home/ion #
…and then tried the address (130.57.66.6) with both Firefox and Vivaldi and here’s the response for both…
Your connection is not secure
The owner of 130.57.66.6 has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

130.57.66.6 uses an invalid security certificate.
The certificate is only valid for the following names:
*.opensuse.org, opensuse.org
Error code: SSL_ERROR_BAD_CERT_DOMAIN
This is way above my level of understanding.
This simply means that the site is properly configured, i.e. IP is correct, but the https certificate is not valid for the IP address, only for the domain name.
