Using Windows, when I started Geth with:

geth --rpc --rpcaddr 192.168.1.9 --rpcport 8545 --rpcapi "eth,net,web3,personal" --datadir C:\Users\BulldogBud\AppData\Roaming\Ethereum\testnet\chaindata --networkid 3 console

Receiving:

I1206 11:55:12.857903 node/node.go:410] HTTP endpoint opened: http://192.168.1.9:8545

I opened another Console typing:

curl -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":1}' http://192.168.1.9:8545

Receiving :

{"jsonrpc":"2.0","error":{"code":-32600,"message":"invalid character '\'' looking for beginning of value"}}

How can I fix this issue? Thank you in advance!

EDIT after several attempts, giving:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_coinbase","params":[],"id":1}' http://localhost:8545

the new error message is:

curl: (7) Failed to connect to localhost port 8545: Connection refused

Any suggestion?

Let use POST MAN

With:

{
  "jsonrpc": "2.0",
  "method": "eth_coinbase",
  "params": ["0x68656c6c6f20776f726c64"],
  "id": 1
}

worked perfectly for me.

Try to set

--rpccorsdomain="http://yourip/"

Or

--rpccorsdomain="*"

Tell me if that work!

Also sometime I use NGROK this way I can create a domain, point to 8545 port and use that domain instead that IP
