Safari Anomaly for TLS Certificate

I have a Wordpress site on a LAMP Stack running in AWS. I have Let's Encrypt running to automatically update the TLS Certificate and I re-direct all traffic to the "www." instance for the purposes of SEO.

The site works as expected for EVERY browser EXCEPT Safari. What I mean is that I've tried Chrome, Firefox, Opera, Vivaldi and Internet Explorer. I made not changes to the Server itself and I'm a little perplexed as to what happened. Below is a screenshot from some testing I was doing using BrowserStack. This seems to be happening on all Safari browsers back to iOS7.

Any idea what's going on here? Is this fixable from my end?

Try running your site through the SSL Analyzer : https://www.ssllabs.com/ssltest/analyze.html

Also, make sure you've correctly issued certificates for both www.yourdomain.com and yourdomain.com

This is helpful because I was able to troubleshoot and diagnose using a Let's Encrypt SAN Certificate.
