Do you have any firewall running?
What is the output of iptables -L?

[wglambert]

Your dial tcp [::1]:6444: connect: connection refused error might involve the /etc/hosts file having an incorrect entry

[Aliabbask08]

@wglambert what entry is needed?
127.0.0.1 raspberrypi-node1
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

127.0.1.1 raspberrypi

[wglambert]

Moving localhost to the 127.0.0.1 line should work
and move the raspberrypi-node1 to the 127.0.1.1 line (presuming it's the actual hostname, and that raspberrypi isn't the true hostname)

Your 6444 port might only be listening on 127.0.0.1, but when you try to connect with localhost:6444 it's translated to ::1:6444 which isn't open

$ netstat -tulpn | grep 644
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 127.0.0.1:6445          0.0.0.0:*               LISTEN      - 
tcp        0      0 127.0.0.1:6444          0.0.0.0:*               LISTEN      -

My /etc/hosts has my hostname as the 127.0.1.1 and localhost is ipv4 only

$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       Ayanami-Clone

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Hosts requirement should be resolved in #750, v0.9.0 Released this fix.

[davidnuzik]

Please try the latest release v0.9.1 as the issue should be resolved. Feel free to reopen the issue if necessary (and provide details of the issue) if the latest release does not resolve this (it should).
