I’ve tried it using Mozilla, Chrome, and Edge as well. You can see right away that it’s a redirect error—bouncing between Cloudflare, Microsoft, and back again. Try using Edge (since Microsoft trusts it the most), then go to Settings > Privacy, search, and services. There, set "Pop-ups and redirects" and "Intrusive ads" to "Allow."
Then close Edge and reopen it. That worked immediately for me.
