If the lab not loading and not responding , my advice is to download Kali Linux on a virtual box and its work will be easier for you and smoother, and it will be your beginning to deal with Kali Linux in a deeper and better way, and I am available for any questions about downloading it. 
Setting up you own lab environment is certainly a great way to get hands on experience. We just can’t promise the lab steps will work in your home lab.
