I’ve read most posts and googled a lot before I posted this.
I pointed my domain to Netlify servers about 46 hours ago. So by now I suppose most propagation should be completed. In my admin panel I can see I have Netlify DNS and I am using https and let’s encrypt. However, I still can’t access my site. The error is NET::ERR_CERT_DATE_INVALID and it was a certificate expired in Apr 2019.
I’m testing on Linux >Chromium + Firefox, both normal and incognito mode, as well as iphone safari + chrome. So far, the iphone doesn’t work at all. And for a brief time today, my site works (and the certificate shown when working is correct as shown in my admin panel) in Chromium and Firefox, but they stopped working once I closed the browser and restarted it. I have no idea why this weird behavior is occurring. I’ve since tried clear the cache and history etc and I also tried Renew Let’s Encrypt button within admin panel 4 times … but nothing seemed to work.
I did ask a friend to check (we’re not using the same WIFI) and it works for him on the phone. The certificate seems to be correct (like when it was working for me briefly).
What could I do to fix this error? Why is this happening?
