cannot connected to server when integrated with docker swarm

[codisan]

I used docker swarm to build a cluster, composed of three machines, A machine is the main node, the other two machines B, C is the secondary node, in this case, my client program cannot connected to server.

I spent three days, still failed to solve this problem， could you help me resolve this issue, please !

Hi @codisan this seems to be a networking issue related to your containers configuration.
if you create a simple http server in your server container, are you able to connect to it from the client container ?
