I run into occasional HSTS issues on my home network sometimes because I've wildcarded HSTS and not everything internal has a cert. It's usually recently arrived IoT stuff that hasn't been cordoned off behind a stronger proxy. Additionally, I run my own internal CA for various reasons and Firefox/Android seems to have stopped recognizing it. Irritating but it's a good razor for whether to upgrade internal or experimental apps to a Let's Encrypt cert.
