[NOOB] Instance problem

Hello, sorry to bother you guys with this. I’m new here(not really new–I got my invite like half a year ago and had to deal with some school exams).

I just simply don’t know how to connect to the pwn instances. I’ve been trying to connect through ssh with “ssh *host -p *port” and it just doesn’t work. Also i checked the other discussion similar to this but it had no productive outcome(here is the link for the discussion: " https://forum.hackthebox.eu/discussion/650/web-challenges-not-loading ").

Any help will be more than appreciated.
