External Javascript file not loading -

i have external third party js file doesn't load in ie 9 or 8. when viewing network tab in developer tools, shows result of aborted. details listed as:

download initiated tokenization of 'src' attribute of 'script' element

and

this download occurred speculative download during html preparsing.

i've searched high , low these terms very few results. i've tried adding script dynamically , changing it's location in layout file, nothing allows file load.

this problem doesn't occur in other browsers, , i've opened security settings on ie hoping browser setting.

any insight or solutions appreciated.

edits:

no cannot see source code. while script listed in dropdown of scripts, doesn't display code in developer tools. i've tried stripping out meta tags , doctype (using html 5), none have moved bar.

script tag: (i'm not including url protect innocent.)

<script src="https://www.internetbankingcompany.org/onlineserv/hb/signon.cgi?remote=true" type="text/javascript"></script> 

it script provided third party financial institutions company, i'm hesitant reveal vendor names. vendor not helpful @ either.

if using jquery's getscript try this:

  $.getscript('script.js')   .done(function(data, textstatus, jqxhr) {     console.log(textstatus);   })   .fail(function(jqxhr, settings, exception) {     console.log(exception);   }); 

what get? callback executed?
