Failed to validate incoming join request from node

I'm trying to set up a simple master-1 node with data-1 and data-2 but when I look at the log I get this error. All nodes are fresh CentOS 7 machine that can ping each other. For all the cluster I've set: playground  <their name master-1/data-1/data-2> [_local_,_site_]
    http.port: 9200 
    discovery.seed_hosts: ["<internal IP of master>"]
    cluster.initial_master_nodes: ["master-1"]
    (at the end):
    node.master: (only true for master-1) true
    node.ingest: false false

Does anyone knows what's going on? Thanks ahead!
