What is the name of the domain?

files.pythonhosted.org

What is the issue you’re encountering

When using 1.1.1.3, the URL: files.pythonhosted.org isn’t resolving to an IP. I’ve checked the domain categorization and it’s not a blocked URL. I think this is an error with Cloudflare DNS.

What feature, service or problem is this related to?

DNS records

What are the steps to reproduce the issue?

Set DNS server to 1.1.1.3 and try to resolve files.pythonhosted.org.

Seems to resolve fine

nslookup files.pythonhosted.org 1.1.1.3
Server:  UnKnown
Address:  1.1.1.3

          199.232.16.223
Aliases:  files.pythonhosted.org

Can you post a screenshot?

I meant to add that “files.pythonhosted.org” is a CNAME.

That is clear, but it still resolves fine.

Hi,

Ok that’s strange then. If I do the exact same nslookup, it just times out for me. I’m wondering if this is local network related.

Thanks for testing.

Might be network related. Maybe your ISP blocks it.
