Steps to reproduce

I read #2854 and #2624 、#2540
I am using https://cloud.dify.ai/apps

My computer is Mac.

  1. I confirmed that Ollama is successfully running;
  2. I disabled all firewall and now all incoming calls are allowed;
  3. I set OLLAMA_HOST to 0.0.0.0
  4. I am not using docker.
  5. I restarted Ollama and rerun Ollama run llama2. I use ollama serve run serve.
  6. I input llama2 in dify backend as model name and http://172.19.0.1:11434/ as base_url
    I still got the same error.
# ✅  I got a result.
curl http://localhost:11434/api/chat -d '{
  "model": "llama3",
  "messages": [
    { "role": "user", "content": "why is the sky blue?" }
  ]
}'

✔️ Expected Behavior

❌ Actual Behavior
