Unable to connect to ssh server

Hi, basic user here. I have set up a windows ssh server on my home lab and installed cloudflare tunnels, i followed networkchucks demo on it. After doing this i can successfully connect using the web based browser fine, but when i try to connect from command prompt i get: connect to host My Host: unknown error.

I followed the guide :https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/use-cases/ssh/ on native tunnels after faffing around getting the msi version of the installer and locating my ssh config file in C:\Users*Name*.ssh\known_hosts i input the values from the guide but im still not having any luck in getting cmd to work? Im under the impression it loads a web page to auth in?

Thank you in advance.
