Joining a cluster not working

 Hey guys,

I'm trying to set up a cluster to test some monitoring features but am having some issues joining a cluster. 

I get the response "Attention - Invalid response from remote node. An error has been logged which may contain more information."

So I checked out my logs and saw this response. I'm sure it's something wrong on my side, any insight would be great thanks!
