Original GitHub issue: https://github.com/ollama/ollama/issues/8711

I am encountering an issue while trying to pull models using Ollama on my Windows 11 machine. The download fails with a DNS resolution error, preventing access to Cloudflare R2 storage, where Ollama hosts its models.

When running:
ollama pull gemma2:2b

Getting Error:
Error: max retries exceeded: Get "https://dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com/...": dial tcp: lookup dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com: no such host

To investigate further, I checked DNS resolution using nslookup:
nslookup dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com

Output:
Server:
Address:
can't find dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com: Query refused

This suggests that my network is unable to resolve Cloudflare R2 storage, making it impossible to pull models.

Steps Taken to Troubleshoot:
✔ Flushed DNS cache (ipconfig /flushdns)
✔ Changed DNS to Google (8.8.8.8) and Cloudflare (1.1.1.1)
✔ Disabled Firewall & Antivirus temporarily
✔ Restarted router and system multiple times
✔ Tried using a mobile hotspot (worked with a different network!)
✔ Tested direct access to Cloudflare R2 (curl, ping) – still unreachable

System Details:
OS: Windows 11
Ollama Version: (Provide your Ollama version here)
Network Setup: Home Wi-Fi
Would appreciate any guidance from the Ollama team on possible workarounds or fixes. Thanks in advance! 🚀

Does your network configure a proxy?

Thanks, given the other issues, it's unlikely it's caused by a proxy but doesn't hurt to double check.

I haven't been able to reproduce this but I've forwarded it to Cloudflare.

There's slightly more info in #8605 so I'm going to consolidate this issue with that
