Problem in docker swarm

General
1

Good day.
Maybe someone help me :slight_smile:
I am install Docker Swarm
In my swarm I have - 1 master and 2 workers
Installed SwarmPit GUI to manage Docker Swarm
all servers in one DC, ping between servers is fine - time=0.242 ms time=0.348 ms

  1. create a network
    docker network create --driver overlay --subnet 10.5.0.0/20 --attachable swarm-test-net
  2. using sonyflake as test app
    docker service create
    –replicas 6
    –network swarm-test-net \
    –update-parallelism 5
    –name sonyflake
    -p 80:80
    titpetric/sonyflake

All is working, problem with this server OVH-167
Can i know what is wrong?
OVH-167 logs is totally fine, i can see - 2019/02/28 16:16:37 Ready and listening on port 80
but I’m sure the problem exists.

Thank you!
