We have an HTML5 Video Player that plays videos. But, when the user wants to jump forward on the video player, it does nothing and it is unable to seek. Obviously, this code works just fine on my own computer; but, once I deploy my application on PythonAnywhere, we're unable to jump anywhere on the HTML5 Video Player. We can only watch the video as it is without jumping forward. Does anyone have any idea how to fix this?
