I get a browser error on my development machine saying ERR_CERT_COMMON_NAME_INVALID. On any other machine there’s no problem
The error includes some info about a Let’s Encrypt certificate I must have set up for that domain some years ago (it expired 2016).
When I ping the domain name on my dev machine I get IP for my web host, however if I ping it on any other machine I get the Cloudflare IP (as expected)
How is this possible?
