Can't load an external javascipt link

Aloha,

I am having a hell of a time trying to load this code below in the HTML block. Is there restrictions on the HTML block so that scripts cannot load? All I get is the loading.... and the script never loads, so I have been searching php code on this for over a week. Thanks for all your support.

<script src="https://authedmine.com/lib/simple-ui.min.js" async></script>
<div class="coinhive-miner" style="width: 333px; height: 333px" data-key="hm2UokSkyUsUIOMB7vgsN7dTxSyT0pB8"><em>Loading...</em></div>

or

<?php echo file_get_contents('https://authedmine.com/lib/simple-ui.min.js'); ?>
<div class="coinhive-miner" style="width: 333px; height: 333px" data-key="hm2UokSkyUsUIOMB7vgsN7dTxSyT0pB8"><em>Loading...</em></div>

It is probably TinyMCE stripping out the javascript.  The key is to turn off the TinyMCE editor; place your code in and save it.

Awesome geek girl, thanks for helping me again!
