Cluster Cache Replication Error

[MP32]

I'm looking at my health checks and I received an error and one of my nodes (The second node I deployed) isn't replicating cache. 

I have my cluster.properties file in each of their home directories and it's populated like-so:

First Node

jira.node.id = node15062
jira.shared.home = /var/sharedhome

Second Node

jira.node.id = node13491
jira.shared.home = /var/sharedhome

Am I missing parameters in these files? What else could I check?
