The problem is in your error message. x10hosting's servers are not proxy servers; they are not the ones refusing the connection nor blocking it. The error message you posted said: "The proxy server is refusing connections", which means that the server you are going through to get to x10hosting is refusing to connect to x10hosting, not the other way around. This means that it is your internet connection specifically that is refusing to connect to x10hosting. There's nothing that x10hosting can do here, because x10hosting doesn't control your internet connection. You'll need to find either a different internet connection to get to your account, or convince your network administrator for your internet to let you connect to your x10hosting account. Good luck. I hope you find a way to connect to your hosting account.
