Hello, I tried to figure this out on my own and I read a few posts that touch on this same subject, but for some reason the posts I found just dont seem to complete (they stop at certain places). So, I’m asking for help to get me past the next step. I am using Docker version 27.3.1, build ce12230 …

just an idea. Are you sure all the mentioned required ports are open between the nodes?

First thank you for the formatting. I failed on that one! LOL second, yes (at least I hope so) all nodes have these ports open: ports: 2377/tcp 7946/tcp 7946/udp 4789/tcp 4789/udp

Wait are you talking port 8080 and port 80?

No, I meant the ports in your previous message.

I’ll add them now and reply with results

ok, so all ports added, 8080 and 80, still same results, it will respond to every other curl, not each one. if I do a curl http://<nodeName1>:8080 it responds curl http://<nodeName2>:8080 will not respond/timeout curl http://<nodeName2>:8080 responds curl http://<nodename1>:8080 will not respond…

When the required ports are opened in the firewall, and it still doesn’t work, the usual suspects are: not using a low latency network amongst the nodes missmatch in mtu size amongst the nodes nodes run in vms on vmware vsphere/esxi A published port of a swarm service should be bound on every nod…

Maybe this topic can provide some new ideas: Docker Swarm - The web service without loading

Creating a Docker Swarm service with a simple port will create an ingress network. All nodes will open the port and Docker will load-balance requests to the replicated service instances. Is the Swarm cluster setup correctly, can you list nodes, services and service instances?

[image] meyay: nodes run in vms on vmware vsphere/esxi this is exactly our environment. I will read the link you posted below, but if there is anymore reading that you can point me to, I’ll be more than happy to read up on that. Thank you, AB
