CHAIN_RPC_UNREACHABLE

RPC endpoint unreachable

What happened

A JSON-RPC call to the configured 0G node failed — network down, DNS error, wrong URL, or rate-limited.

How to fix

Run 0g doctor to ping the configured RPC. If your network is fine, the public Galileo RPC may be rate-limiting — provide your own via --rpc or ZEROG_RPC_URL.

Example

0g doctor
0g chain balance 0xabc... --rpc https://my-own-galileo-rpc.example
