This is likely #8605, although switching DNS servers usually fixes it. Follow the instructions in https://github.com/ollama/ollama/issues/8605#issuecomment-2639100703 and post the results.

I run following commands and test the endpoint dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com using mxtoolbox.com I am getting following issues and errors. It looks like someone deleted records from hosted zones.

Note.
It is work in mobile/Celluer data/internet provider but if you use star link like JIO Fiber like providers.

same problem

dial tcp: lookup ...r2.cloudflarestorage.com: no such host — DNS record missing from Cloudflare R2 (not local issue)

What is the issue?

Running ollama pull or ollama run results in a DNS error:

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

This happens regardless of internet connection or DNS provider used. MXToolbox confirms the domain is not resolving publicly — indicating the issue is with Cloudflare DNS configuration, not the client environment.

What happened? What did you expect to happen?

Expected Ollama to pull and run models normally.

Instead, model pulls fail with a no such host error due to DNS lookup failure on Cloudflare R2 object storage.

I expected the DNS record dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com to resolve successfully. However, it does not exist publicly — and appears to have been deleted or is misconfigured.

nslookup r2.cloudflarestorage.com
Server:  UnKnown
Address:  10.58.11.4

DNS request timed out.

What I’ve tried (to rule out client-side problems)

  • Changed DNS to 1.1.1.1 and 1.0.0.1
  • Flushed DNS (ipconfig /flushdns)
  • Switched to mobile hotspot
  • Disabled firewall + antivirus
  • Confirmed DNS lookup fails using nslookup and ping
  • Tried test models from Ollama’s staging server (e.g. issue1736.ollama.dev/library/llama3:8b) — still fail
  • Verified with [MXToolbox](https://mxtoolbox.com)

MXToolbox DNS Diagnostic Results

Used [mxtoolbox.com](https://mxtoolbox.com) to test dd20bb891979d25aebc8bec07b2b3bbc.r2.cloudflarestorage.com and cloudflarestorage.com. The following issues were found:

DNS Errors

  • No A record found
  • No DMARC / SPF / DKIM records
  • SOA Serial Number format is invalid
  • SOA Expire Value is out of range
  • HTTP request timed out (connection to root domain failed)

Name Servers

  • No recursive name server detected
  • Name servers are valid but report no data for the R2 bucket subdomain

This confirms that the DNS record is missing or broken at the origin, not blocked on the client side.

It doesn't have an MX record because it doesn't receive email so using mxtoolbox.com doesn't provide any useful information.
