Low timeout when doing snapshots from Datatoolbox-app?

Looks like the snapshot it created but you get an error in the logs and in the gui

ERROR s.r.enonic.datatoolbox.RcdScriptBean - Error while creating snapshot
org.elasticsearch.transport.ReceiveTimeoutTransportException: [myserver.no][inet[/]][cluster:admin/snapshot/create] request_id [534921] timed out after [5016ms]

Not linked to Datatoolbox. It comes from Elasticsearch and seem to be a timeout between 2 nodes of your cluster.
Do you reproduce for every snapshot and only on snapshots or is it a random error?

I get it on every snapshot. The cluster state is green btw
