Maybe, but how do you explain my phone also having the same problem? A couple of times I’ve tried to renew the Let’s Encrypt certificate and nothing happens, the date stays the same. Maybe that’s how it’s supposed to work, I don’t know. My Netlify sub-domain for this site has not had this problem so I’m thinking it’s certificate related. We’ll see what happens in the next few days.
Update - here are 2 screenshots showing the problem.
I’m unable to replicate the issue as well. The site loads properly with SSL. I’ve also tried Firefox and it also loads correctly. I also see that you’re using Netlify DNS and Netlify’s name servers are correctly configured:
