I recently installed 4 new droplets to try out docker swarm/rancher/kubernetes etc.
Three of them works perfectly, but one of them can for some reason not connect to the other ones.
ufw is disabled on all of the droplets, and all I’ve done on each machine is to add a user password, and install docker…
I’m not sure if this is enough information to go on, but all the help I can get would be greatly appreciated
