Page throws TLS error instead of loading

I've researched this up the wazoo but to no avail. I have a page internally that requires TLS 1.1 or 1.2. If they're not on, you get an error:

This page can’t be displayed

Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try
connecting to https://SITEADDRESS again. If this error
persists, it is possible that this site uses an unsupported protocol
or cipher suite such as RC4 (link for the details), which is not
considered secure. Please contact your site administrator.

Obviously the fix is to turn on those cipher suites in IE. However what I would like to put into the page is a check, to preload something from the site, make sure it's visible/readable/loadable/whatever, then allow the user to move forward, OR, if whatever it is I'm checking cannot be rendered/read/etc, direct them elsewhere.

So what I've tried was doing a PHP file_get_contents of the SAME address

<?php

$contents = file_get_contents('https://SITEADDRESS');

echo "<pre>";

var_dump($contents);

echo "</pre>";

?>

However, it ends up being able to pull the page code and dump it out?!?!!? Which means it CAN access the page, yet, I know it can't because I get a TLS error when trying to load it normally.

The question is, how can I precheck a URL with TLS as a consideration before forwarding the user on to a page that might not render?
