Ethereum client-go RPC response 403 invalid host specified

Question

I'm running ethereum/client-go docker image with the following flags:

docker run -p 8545:8545 ethereum/client-go --rpcapi personal,db,eth,net,web3 --rpc --rpcaddr 0.0.0.0 --rpccorsdomain * --rinkeby

This image is running on machine A and I can query the RPC within it. But when I try to query it from machine B I receive the following response:

Request:

curl -X POST http://<machine_A_address>:8545 -H "Content-Type: application/json" --data '{"jsonrpc":"2÷.0","method":"eth_coinbase","params":[],"id":64}' --verbose

Response:

< HTTP/1.1 403 Forbidden
< Content-Type: text/plain; charset=utf-8
< X-Content-Type-Options: nosniff
< Date: Wed, 18 Apr 2018 14:58:44 GMT

invalid host specified
* Connection #0 to host ... left intact

How can I query the ethereum client hosted on machine A from machine B ? Where I can find the ethereum client logs so I can debug it ?

Answer 1

Adding --rpcvhosts=* should solve the issue
