Docker stack deploy service not listening to port

Docker Engine Swarm
1

I am running into interesting situation, everything worked couple of weeks back but now my swarm if behaving strange. I have swarm with two nodes, one is manager (ip = x.y.z.100) another is worker (ip = x.y.z.101)

I run stack deploy using following docker-stack.yml

version: "3"
services:
  my-app:
    image: my-app    
    ports:
      - "8090:8080"
    deploy:
      mode: replicate      replicas: 2
      labels: [APP=MY-APP]
      update_config:
        parallelism: 2
      restart_policy:
        condition: on-failure
      placement:
        constraints:
          - node.role == worker
  visualizer:
    image: dockersamples/visualizer
    ports:
      - "8080:8080"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    deploy:
      placement:
        constraints:
          - node.role == manager
  apache-php:
    image: apache-app    
    ports:
      - "80:80"
    volumes:
      - /home/docker/apache-app/000-default.conf:/etc/apache2/sites-enabled/000-default.conf
      - /home/docker/apache-app/resources/my-viewer:/var/www/html
    deploy:
      placement:
        constraints:
          - node.role == manager

after stack deploy, there is no error message everthing seems to be working fine. Also docker container ls or docker service ls, i see all the container and services as expected.

Problem is, if i want to access visualizer with x.y.z.100:8080, i get cannot make connection. So I checked
sudo netstat -nlp | grep 8080
sudo netstat -nlp | grep 8090
sudo netstat -nlp | grep 80

and it does not show anything listening on these port, but if i run the same thing on x.y.z.101, i see 8090 is being used by my-app, as expected.

Also if run container using docker run, things work fine.

Thanks in advance for any suggestion and help.

Seems like this is the bug reported here:

I restarted both the manager and worker and now things are working again, phew!! what a waste of time.
