I am trying to create an elasticsearch cluster with several nodes, I have 3 master nodes, but every time they try to join it gives this error.

```auto

Hey @Julio_Edel_Salas_Dia, there's not a lot of information in this single log message except that the node took over 60 seconds to join the cluster and hit a timeout. To get a more useful answer you'll need to share all your logs from all the nodes. Use something like [https://gist.github.com/](https://gist.github.com/) since there will be more information than will fit in a post here.

(I've reformatted your logs; please format your posts carefully in future or else they're likely to get ignored)

@DavidTurner  
From the previous problem I found a partial solution: if I put all the nodes on the same host there is no problem, it does not work when on different hosts (servers) and log something like this:

`spacesorg.elasticsearch.transport.ReceiveTimeoutTransportException: [emc-master-02] 10.28.11.7:9300][internal:cluster/coordination/join/validate] request_id [48] timed out after [60035ms]`

I can't really offer any advice from this tiny fragment of information alone.
