Plugin using incorrect url and I can not find where it is

I have a plugin that I am trying to get to load ads in the side bar
however the java script url it is trying to load is the wrong url

and the plugin file has the correct url in the java script so I can not figure out where the url is being pulled from

using the developer tools in chrome its showing the following

Failed to load resource: the server responded with a status of 404 (Not Found)
I need a fresh seat of eyes viewing the issue and a little help
