Node to node connection failes

Question

Hi,

I was trying to create new node - node4 on blockchain1 server (192.168.1.81) by retrieving
blockchain parameters from the seed node 192.168.1.82:8369 (node6), which is on different
server - blockchain2 (192.168.1.82).
When I try to connect to it I get following error:

[nprnic@blockchain1 ~]$ multichaind nchain1@192.168.1.82:8369 -datadir=/home/nprnic/node4 -rpcport=8370 –port=8371
MultiChain Core Daemon build 1.0 alpha 15 protocol 10003
Retrieving blockchain parameters from the seed node 192.168.1.82:8369 ...
Error: Couldn't connect to the seed node 192.168.1.82 on port 8369 - please check multichaind is running at that address and that your firewall settings allow incoming connections.

Node6 is up and running and I can do getinfo without any issues and the firewall is disabled:

Using username "root".

● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
[root@blockchain2 ~]#

Is there anything else that may cause node6 not to be accessable to node4?

Answer 1

It may be the wrong IP address, if that is just the local IP address but there's another globally accessible one. Try ifconfig -a to list all IP addresses and substitute in the node address instead of 192.168.1.72

Could still be a firewall issue and you can try connecting to the port over telnet to check.
