Hey , so I set up a server called ^27(colour) Training Server and I was the OP for a time , but I quit toribash to do other stuff and when I came back about an hour later I wasn't the OP (but my name was still green) , I'v tried disconnecting my dongle (wifi) and my house router , but the server doesn't close and I'm not the OP of it.

Could someone help me either close the server or let me regain OP power

The server closes down once it's empty. Just make a new server, and you'll be op there.

Thanks , thread solved

To become operator again you would have to set an extra password when you are operator. The command is /setowner [password]
When you leave the room you can come back later and type /owner [password] to become an operator again. As long as the room is still opened of course.

Closed upon request.
