I am completely unable to use the sandbox environment while taking the Graphacademy courses. My browser considers the inline connection to the sandbox as insecure. At one point I was able to get around this by opening the sandbox URL in another window. This no longer works. There is something about an insecure websocket connection. I have no idea how to fix this. I am incredibly frustrated.
