# CONFIG_INVALID_NETWORK

**Unknown network name**

## What happened

The `--network` flag (or `ZEROG_NETWORK` env var) was set to a value that doesn't match any known preset. Valid values are `galileo`, `aristotle`, and `local`.

## How to fix

Pick one of the supported networks, or pass an explicit RPC URL via `--rpc` if you're targeting a custom node.

## Example

```ts
0g chain balance 0xabc... --network galileo
# or
0g chain balance 0xabc... --rpc https://my-custom-rpc.example
```
