Origin Null when fetching data with XMLHttpRequest

I'm trying to fetch some data from a public API. When I open the URL in the browser I get the needed JSON, but when fetching it I get this ERROR.

[Error] Cross-origin redirection to https://sv443.net/jokeapi/category/Any denied by Cross-Origin Resource Sharing policy: Origin null is not allowed by Access-Control-Allow-Origin.

This is my code:

let jokeUrl = "http://sv443.net/jokeapi/category/Any";

let xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if (xhr.status == 200) {
    console.log(xhr.responseText);
  } else {
    console.log("There was an error: " + xhr.status);
  };
};
xhr.open('GET', jokeUrl, true);
xhr.send();

I was able to get a response by changing the url from http to https.
