Debug Heroku App on Visualforce Page

We have a Visualforce page that has Script from a Heroku App that suddenly stopped working. I'm not familiar with Heroku and I believe our previous Salesforce Admin wrote the code. Is there a way from Salesforce to access a Heroku App? Is the previous admin the only person who would have access to this?

The script starts like this:
 
<script type="text/javascript">
    var host = "https://(ourcompanyname).herokuapp.com";

With (ourcompanyname) showing one of our domains. I don't have a Heroku login and I don't know if creating one will give me access to this speicfic app.
