Try ollama-downloader. It has worked for me even behind a HTTPS proxy with a self-signed certificate, behind which ollama pull did not work for a single model, failing with the SHA256 check despite being able to download all BLOBs. (Disclaimer: I am the maintainer of the ollama-downloader project.)
