All "docker swarm or node" commands fail with "Error response from daemon: 404 page not found" (Cluster on Microsoft Azure)

Hello,

I have deployed a cluster on azure with azure docker swarm template from portal.azure.com.

I have one master VM on azure and 5 nodes (2 started and 3 stopped) on 5 VMSS on azure.

I’m running 6 instances of nginx server (only for spreading test on two nodes).

swarm-agent-D3C8D65D000000 : node #1
swarm-agent-D3C8D65D000001 : node #2

xxx@swarm-master-D3C8D65D-0:~$ docker -H tcp://localhost:2375 ps

Swarm agent is started on master (version 1.1.0) :

xxx@swarm-master-D3C8D65D-0:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0b357adcd51f swarm:1.1.0 “/swarm manage --repl” 5 days ago Up About an hour 0.0.0.0:2375->2375/tcp containers_swarm_1

Now, I want to stop node #2. To do this I would like to drain node #2.

xxx@swarm-master-D3C8D65D-0:~$ docker -H tcp://localhost:2375 node ls # To list nodes
Error response from daemon: 404 page not found

Or

xxx@swarm-master-D3C8D65D-0:~$ docker -H tcp://localhost:2375 swarm join-token worker
Error response from daemon: 404 page not found

Etc …

All commands “docker swarm or node” fail with : " Error response from daemon: 404 page not found".

Correctly, it’s impossible to drain and remove the swarm agent #2 to stop the VMSS #2.

Do you have any idea to resolve this problem?

Thank you in advance to any one who may be able to give me some ideas and excuse me for my poor English.

I got exactly the same issue did you find a way to solve it?
