erlang epmd is not operational

Question

I am trying to connect ejabberd to node on remote server, but can't ping node. Both node running with -name '[email protected]' and -name '[email protected]' with kernel options -kernel inet_dist_listen_min 4370 inet_dist_listen_max 4370 , port 4370 is accessible (checked it with telnet on host1.my):

telnet host2.my 4370
Trying 34.252.148.114...
Connected to dt.mantu.im.
Escape character is '^]'.

in erl:

   net_adm:names(). 
    {error,address}

that mean epmd is not operational, but

/usr/lib/erlang/erts-9.1.5/bin/epmd -names
epmd: up and running on port 4369 with data:
name dev at port 4370

Answer 1

Port 4369 (epmd daemon port) also should be open
