I've been waiting for the cluster version of Apache IoTDB for a long time so I installed preview version 0.14 as soon as I can. However when I try to set up access configuration, the connection was denied by host IP access. I tried another local host IP,localhost/123.0.0.1,and the access is available. I set rpc_address as 0.0.0.0 and rpc_port as 6667. Any suggestions on how this can be solved?
