Failed: No route to host

Docker Engine Swarm
1

I have 20 nodes in swarm.
I use Stacks deploy a service like this

version: ‘3’
services:
cadvisor:
image: cadvisor:v0.24.1
environment:
- TZ=Asia/Shanghai
volumes:
- /:/rootfs:ro
- /var/run:/var/run:rw
- /sys:/sys:ro
- /var/lib/docker/:/var/lib/docker:ro
deploy:
mode: global
ports:
- 7080:8080
networks:
- monitor-overlay

networks:
monitor-overlay:
external: true

All nodes work except 192.168.1.238

wget 192.168.1.238:7080
–2019-04-02 10:45:01-- http://192.168.1.238:7080/
Connecting to 192.168.1.238:7080… failed: No route to host

why?
what information should I need paste here?
we don’t run firewall

I found in Container
192.168.1.238 IP of monitor-overlay is 10.253.0.23
in other docker Container can
wget 10.253.0.23:8080
it works.
