Connection Refused

I tried to go to my website but I got error "ERR_CONNECTION_REFUSED". Then I tried to go as wordpress admin but I still got it, I tried the same on my other website and I got the same error. Can anyone help please? This error isn't only on my device, I tried to visit the website from other devices with different internet connection too.
EDIT: I also tried to reactivate my old website that I didn't use and it gets the same error when I try to visit it. Profreehost also showed error after activating it: "An error occured while trying to reactivate account". I don't think that this is because of Wordpress isn't installed, because it says Wordpress is already installed.
