Right, that sounds like something is blocking the main domain, Since your site is a subdomain of wuaze.com it could also be blocking that.
So now we know that, we need to work out what is blocking the domain for you.
There are 4 things that I’ve seen multiple times that block free hosting domains:
Your Virus Scanner can sometime block domains. If possible add your site to your virus scanners whitelist. That might fix it
Your Firewall - Same as above
Network Admin, this generally is only a problem if you’re using a school\collage\uni or work network. If this is the case, you’ll need to talk to your network admin.
Your ISP. While unlikely from the error message you’re getting, its possible that your Internet Service Provider are blocking the domain. You’d need to reach out to your ISP about this.
Potentially the quickest way arround this might be to use a VPN. Some browsers (like opera gx) come with a free VPN you can try to see if it works
