Wondering if something change with a recent change? I was following this guide: [Scaling Large Language Models to zero with Ollama · The Fly Blog](https://fly.io/blog/scaling-llm-ollama/) to setup ollama. I was able to deploy the actual ollama server and was able to create a ephemeral machine to connect to the server.

The steps say I should be able to run ollama commands but they are returning no such host errors

Am I missing something? Do i need to open ports to get the tutorial working?

Assuming there isn’t a bug in the fly blog, you probably typed in the wrong `OLLAMA_HOST` value? It’s trying to hit the `fly.dev:11434` host, which is wrong. It should be hitting the internal flycast host.
