I've built a website and have used certbot to create SSL certs.
The page loads fine on every system I've tried it, except in Chrome on my phone.
In Chrome, on the phone (Android), I get NET::ERR_CERT_AUTHORITY_INVALID
In FF on the phone it loads fine. In Chrome or FF on my tablet it loads fine. In Chrome or FF on laptop and/or on desktop it loads fine.
What's up with Chrome not playing nice?
