Description

Description:
EMS server is started with listener port as following:
listen    = tcp://8222
or
listen = tcp://localhost:8222

EMS admin client will fail to connect to the local EMS server using the following connect option:
using port only e.g. "connect 7204"
or
using localhost e.g "tcp://localhost:7204"
Symptoms:
This may happen to the EMS admin client after 6.3 version which provides support for IPv6 (Linux and Windows) and the machine has IPV 6 disabled.

Cause:
EMS uses getaddreinfo()  to return all loopback addresses. It also returns IPV6 loopback addresses even if IPV 6 is enabled.

The following JIRA issue was logged which will be addressed in a future release:
EMS-6194
EMS should abort the connection attempt when connect() returns anything but OK or EINPROGRESS for non blocking sockets.

Resolution

Enable IPV 6 or use the specific hostname or IP address for listening/connecting from/to the EMS server.
