Contributor Author. It was a page rule at Cloudflare. Fire OS 7 is based on Android 9. I never clicked on the other link checked with browser history - just the same one 3x so I assumed you had just revoked it in real time. There were some issues recently with certs provided by LetsEncrypt on some older devices - but I use LetsEncrypt myself and even on Gen 2 FireTV devices, I did not experience any issues.
