Unable to connect with Telnet - Connection closed by foreign host

The following error is occurring as I try and follow along with the video :

telnet httpbin.org 80 Trying 54.175.219.8... Connected to httpbin.org. Escape character is '^]'. GET/HTTP/1.1 Host : httpbin.org Connection closed by foreign host.

-As soon as I press enter after the "Host : hhtpbin.org" command, I get the error message before I can even press enter again.

I've tried accessing the resource at the mentioned address, and I found it successfully (as of Mars 2017).

Based upon your input, GET/HTTP/1.1 should cause a 400 Bad Request since the syntax is incorrect. There must be whitespace between the GET and / as well as after the / since the forward-slash refers to the root. Furthermore, the host confirmation on the request line that you've specified is incorrect, it must be httpbin.org.

So, it must be as following.

telnet httpbin.org 80

Once a connection has been established, and the prompt is open for input again. Enter.

GET / HTTP/1.1
Host: httpbin.org

You must type the request line quickly because of the inner workings of Telnet. Secondly, you must perform a carriage-return twice in order to submit the request.
