# M303: Local provider unavailable on Cloud

> M303 is returned when LLM Gateway Cloud is asked to use Ollama, LM Studio, or llama.cpp.

## What you saw

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
[🦚 Manifest M303] Built-in local providers are only available in self-hosted Manifest. On Manifest Cloud, expose the runtime through a public URL or tunnel and connect it as a custom provider.
See https://manifest.build/llm-gateway/docs/errors/M303
```

## Why it happened

The built-in [local provider](/llm-gateway/docs/llm-gateway/docs/providers/local-models) tiles (Ollama, LM Studio, llama.cpp) route to `localhost`. On a self-hosted install that's your machine, which is the whole point. On LLM Gateway Cloud, `localhost` is our server, which has no model running on it and no route back to your laptop.

Rather than dial an address that can't be yours, the gateway stops the request here.

## How to fix it

Pick whichever fits:

<Tabs>
  <Tab title="Self-host">
    Local providers work as designed on a self-hosted install, and your prompts
    never leave your network. See [Self-hosted](/llm-gateway/docs/llm-gateway/docs/self-hosted) for the one-line
    Docker install.
  </Tab>

  <Tab title="Custom provider">
    Keep using Cloud and give your runtime a public address. A tunnel
    (Cloudflare Tunnel, ngrok, Tailscale Funnel) is the usual way. Then add it
    under [Custom providers](/llm-gateway/docs/llm-gateway/docs/providers/custom-providers) using the public URL
    instead of the built-in tile.

    Put authentication in front of it. A public URL with no key is an open
    inference endpoint that anyone can bill to your hardware.
