Quick connect domain problems

Hey, I have used the quick domain option to publish a site. This domain has already been in use and paid for. Originally it was used on the WIX site, which I logged in and tried to transfer through the quick domain option but it said ‘failed’ and now when I try and search for the site, it doesn’t work at all. So now I am lost with how to use that domain or what to do next?

here is my read me

This is what comes up when i type in the website

Would appreciate if someone can help me with this, thank you
