The last things I want when in the middle of development is the client poking around.
Code should be on Github/Bitbucket and you should have full access to it. Database schema should be there too. You want a database dump? Ask for one. If they don't provide, hire someone to reset access and fire them.
But don't poke around the server in the middle of their work because you're curious. That's a dick move.
> Anyway because of this I tried to use the terminal option to access my server but I got a 'port 22: Connection refused' error.
Oh good, your developer isn't as much of a halfwit as you. He either set up a firewall restricting access to his IP or he changed the port sshd is on.
TALK to him. Ask him to do what you want. If he refuses, hire somebody who knows what they're doing to fix the mess.
