Where is the etc folder?

Hi, this might be a pretty stupid question but where is the /etc folder in PLESK? I always thought it is directly below the root but there's no /etc folder.

I tried to connect via SSH but all I get is "
ssh: connect to host xx.xxx.xx.xx port 22: Connection refused"

I already set it to /bin/sh but still not working.

Thank you very much in advance.
