MinIO Distributed on Docker Swarm Error: "Invalid command line arguments: no endpoint pointing to the local machine is found."

Question

I'm pretty new to docker but for the life of me can not figure out what is going on here. The directory /export exist on each vm in the swarm but it still complains about not being able to find a suitable endpoint? The docker installation was done by following the directions for "Install using the repository" section from the docker website located here: https://docs.docker.com/engine/install/ubuntu/.

Steps to reproduce the error:

4 virtual machines running Ubuntu 20.04.5 LTS and Docker 20.10.18, build b4oc2f6

Create the swarm by running the following command on the manager:

root@dkrswpmgr:~# docker swarm init --advertise-addr 172.16.30.179

Then the docker swarm join command on each of the worker vm's

root@dockerswarmworkerthree:~# docker swarm join --token SWMTKN-1-147p8fclfc1lmlbefkowg2xms02drt9m4bffzt3eq08ox12v1f-c3ij2nnyqfo15bxl3fg9pzmcx 172.16.30.179:2377

Then to verify the swarm is correct run docker node ls on the manager node:

root@dkrswpmgr:~# docker node ls
ID                            HOSTNAME            STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
bjrr8rqa55u686r0n6qw1yh37     dkrswnworkertwo     Ready     Active                          20.10.14
slq6p97k49c3patnkqj459jbx *   dkrswpmgr           Ready     Active         Leader           20.10.14
z5e3wk78f75yg8t1u34tny0gf     dkrswpworkerone     Ready     Active                          20.10.14
3i92etwcwo45dgavoz2l4n1nk     dkrswpworkerthree   Ready     Active                          20.10.14

Now the swarm looks good and the directory /export exists on each machine, set the ACCESS and SECRET KEYS as docker external environment variables:

root@dkrswpmgr:~# echo "$(openssl rand -base64 21)" > ACCESS_KEY
root@dkrswpmgr:~# echo "$(openssl rand -base64 41)" > SECRET_KEY
root@dkrswpmgr:~# cat ACCESS_KEY | docker secret create access_key -
root@dkrswpmgr:~# cat SECRET_KEY | docker secret create secret_key -

Grab the MinIO distributed yaml file from here:

root@dkrswpmgr:~#  wget https://git.shivering-isles.com/github-mirror/minio/minio/-/raw/df884210873b75116e98f0d7bb709e9a2e12ad29/docs/orchestration/docker-swarm/docker-compose-secrets.yaml

Deploy the service to the swarm:

root@dkrswpmgr:~# docker stack deploy -c docker-stack.yml MinIO
Creating network MinIO_minio_distributed
Creating service MinIO_minio3
Creating service MinIO_minio4
Creating service MinIO_minio1
Creating service MinIO_minio2

Look at the logs:

root@dockerswarmmanager:/home/e3rb0s# docker service logs minio_stack_minio3
minio_stack_minio3.1.d1hcolw4b3s6@dockerswarmworkerthree    | ERROR Invalid command line arguments: no endpoint pointing to the local machine is found.

The error is the same for all vm's belonging to the swarm.
