Hi @Ajay-Engineer access to cloudflare is required to download models via ollama pull. In the future this will be behind a custom domain such as models.ollama.com which should help in environments with firewalls

Hello, Everyone!

At Ollama we're working on a solution to this issue, and have been seeing some positive results!

Now we need your help testing in your enviroments as well!

How to help:

  1. Run a test pull through our staging server

    From the list below, pick one (or many) of the models that you have not pulled already, and perform a pull.

    ollama pull issue1736.ollama.dev/library/llama3:8b
ollama pull issue1736.ollama.dev/library/gemma:2b
ollama pull issue1736.ollama.dev/library/mistral
ollama pull issue1736.ollama.dev/library/dolphin-mistral
ollama pull issue1736.ollama.dev/library/wizardlm2
ollama pull issue1736.ollama.dev/library/llava-phi3
ollama pull issue1736.ollama.dev/library/llava-llama3
ollama pull issue1736.ollama.dev/library/dolphin-phi
ollama pull issue1736.ollama.dev/library/nomic-embed-text
ollama pull issue1736.ollama.dev/library/phi3
ollama pull issue1736.ollama.dev/library/orca-mini

  2. Remove and retry 2 or 3 more times

    ollama rm issue1736.ollama.dev/library/<model>[:<tag>]
ollama pull issue1736.ollama.dev/library/<model>[:<tag>]

  3. Report back!

    Please respond here answering these questions to the best of your ability:

    • What was the full ollama pull command you ran including model?
    • What OS are you running the ollama server on?
    • What speed range did you see? (e.g. 30-50 MB/s)
    • What version of Ollama are you using?
    • What region of the world is your ollama running?
    • What is the top speed of your internet connection?
    • Was it faster, slower, the same as a normal ollama pull <model> for the same model(s)?

Thank you all so much in advance. We look forward to hearing back from you.
