Hi,
When i try to access the web demo, it gave me this error -> 504 gateway time-out
is it due to my proxy server? And in the function of web demo below
function json_rpc_send($host, $port, $user, $password, $method, $params=array())
what should i pass into the $host? it's the rpchost which is IP address of MultiChain node (my client real IP address?)
