Hello everyone, I am trying to form a Docker Swarm with a manager node and 2 workers. The problem is that the worker nodes do not join the swarm, and they show me the following error:

Docker Engine Swarm
1

Error response from daemon: Timeout was reached before node was joined. The attempt to join the swarm will continue in the background. Use the “docker info” command to see the current swarm status of your node.

Without any hint about your system and what you did exactly, it’s hard to support and diagnose.

It seems the nodes can not connect to each other, have you tried a ping? Is there a firewall in between?
