Hi,

Running MongoDB version 3.4.9 on two separate servers running Centos 7.

Trying to add a create a replica set but when ever I try to add a second server I get this error:

devshardcfgrs:PRIMARY> rs.add("s2-b6:26052") { "ok" : 0, "errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only t he following 1 voting nodes responded: s1-b5:26051; the following nodes did not respond affirmatively: s 2-b6:26052 failed with No route to host", "code" : 74, "codeName" : "NodeNotFound"

What am I doing wrong?

This is my /etc/hosts file:

127.0.0.1 localhost

::1 localhost

172.24.1.42 s1-b5

172.24.1.43 s2-b6

All help is appreciated :)

    Connor, seems like you have two accounts. You can merge them to avoid further confusion and be able to edit your question directly.

    Connor, since it seems like JJussi's answer worked for you, you should mark it as an accepted answer instead of editing your question.

Firewall! Go to the command line of s1-b5 and give command mongo --host 's2-b6:26052' you should have a successful login to "second" node. I guess that these two nodes are actually one machine?!? And when you use "external IP address", traffic goes thru the firewall. So, iptables-save command should show that this port 26052 is open for traffic.
