can't get telnet to work? use postman

I could not get telnet to work on my admin cmd window or treehouse workspaces ... instead I went to chrome Postman and type httpbin.org:80/ and httpbin.org:80/treehouse to mimic what the instructor was doing

You can enable telnet by running,

dism /online /Enable-Feature /FeatureName:TelnetClient

PS: You will need administrator privileges to run this command.

If you're having problems using Telnet on workspaces, please contact support at help@teamtreehouse.com, and include the details of your OS & browser. In any case, doing the following on workspaces should work:

telnet httpbin.org 80

GET /html HTTP/1.1
Host: httpbin.org

[press ENTER twice]

I have noticed that, sometimes, httpbin.org can be slow to respond. So be sure to give Telnet enough time to receive the response. It took about 15s to get the response from above. You could also try another website, such as Google, which is super quick:

telnet google.com 80

GET / HTTP/1.1
Host: google.com

[press ENTER twice]

I get a response from this right away, though it is a redirect:
