Docker Swarm Portainer Communication issue

Hello,

Deployed docker swarm with two additional nodes. Cannot seem to get portainer agent to respond on port 9001. Not fully understanding why. Are there any tricks to getting this to work?

I see this inside the logs that makes me somewhat concerned:

2023/10/31 12:32AM WRN github.com/portainer/agent/docker/docker.go:79 > agent container running in more than a single Docker network. This might cause communication issues | network_count=2

Having two networks in swarm mode is normal. Don’t worry.

How does “does not respond” manifest?
