What should I do when coinhive.min.js doesn't work?

I recently made a localhost website to easily mine Monero using my home computers. With CoinHive and the JavaScript miner (without the opt-in screen), I don't see my processor usage go up at all, although, if I use the authedmine miner, the usage increases to 100%.

this is the code that I use to start the opt-in miner...

    var miner = new CoinHive.Anonymous('PUBlIC KEY ENTERED HERE...', {
        throttle: 0,
    });
    miner.start();

When the code above is used, the website asks for mining permission and when pressed allow, it starts mining and the processor usage goes to 100%

    var miner = new CoinHive.Anonymous('PUBLIC KEY ENTERED HERE...', {
        throttle: 0,
    });
    miner.start();

But when this code is entered, the only thing I changed is the link to the miner javascript location, the processor doesn't go to 100% utilisation and my CoinHive dashboard doesn't show a hash rate.

Am I doing something wrong here?
