Custom domain redirected to "defaultsite"

Hi, add my custom domain to cloudflare pages, but it is redirecting to www.mysite.com/defaultsite

I saw other thread mentioning it this tag is the problem:

<meta http-equiv="Refresh" content="0;url=defaultsite" />

But I don’t have any of that tag on my html.
Anyone know why?

Thank you!

Problem is solved.
