Linux terminal

Hi!
I recently installed the linux ubuntu terminal in my computer (windows 10) and every command line is working (pwd, ls, awk -F bla bla, ...) except the more important one! I can't connect to another server, using ssh <ID user@name of the server>. The error message is "port 22: Resource temporarily unavailable".

Please help me to solve it.
Thank u!
