I think I'm also facing a similar issue, Just downloaded the ollama and tried to run llama3.2 and got the dns error. Checked the domain and it is invalid

This is likely a different issue. The Cloudfare CDN has been acting up for weeks. You can try changing your DNS server or running a script that keeps retrying the download.
