<div dir="ltr">You can create a process that calls erlang:monitor_node(Node, true) for all nodes expected to be in the cluster. Then whenever you receive a {nodedown, Node} in that process you can monitor_node the failed node after some cooldown time. Since monitor_node will attempt to connect to the node if it's not already connected, this would be enough to restore failed connections.<div><br></div><div>Cheers,</div><div>Daniel</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 30 Nov 2021 at 06:57, saket chaudhary <<a href="mailto:saketcmf@gmail.com">saketcmf@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">There're no firewalls to speak of.
