Refuting a suspect message (from: <Server>.<something>.com)

I see a lot of warning in the consul_server log, I see it from almost all the machines in the cluster (about 90) :
[WARN] agent.server.memberlist.lan: memberlist: Refuting a suspect message (from: )

The cluster seems to function without any issue. There is no firewall or IP restriction.

Can anyone help me to understand if those WARN messages are any indication for wrong configuration or something wrong in the cluster.
