Minority of my website visitors (maybe less than 1%) are reporting to me that they couldn’t access my website. They all are using older versions of devices and web browsers.
I was curious and wanted to test too. Unfortunately, my older devices are only iphone on iOS8, and an IE11 on windows 8.1. I can confirm these devices couldn’t access my website.
The error message was:
iOS8:
Safari cannot open the page because it could not establish a secure connection to the server.
IE11:
This page can’t be displayed
However, I could load the website using either Chrome, Firefox, and Opera on the same machine which has problem with IE11.

I’m quite not sure the version of certbot client, since I use directadmin. However, this is the second line of /usr/local/directadmin/scripts/letsencrypt.sh
#VERSION=1.1.39
I can login as a root on my machine which is CentOS8. Thank you!
