Docker swarm redis connectivity issue - docker

Question

I have following docker-compose.yml redis config.
version: '3.5'
services:
db:
image: redis:latest
command: redis-server --bind 0.0.0.0 --appendonly yes --protected-mode no
ports:
- target: 6379
published: 6379
protocol: tcp
mode: ingress
There are two hosts leader-0 (manager) and redis-0 (worker)
> root#leader-0:~# docker node ls
ID HOSTNAME STATUS
46tmallxr4l8xr7i90vlwntjq * leader-0 Ready
mofbedj4sqlxgnyatbxhlokc7 redis-0 Ready
Redis host redis-0 exposes 6379 port on the localhost as expected:
> root#redis-0:~# redis-cli -h 127.0.0.1 ping
PONG
but 6379 is not available on the manager (although it should):
> root#leader-0:~# redis-cli -h 127.0.0.1 ping
Could not connect to Redis at 127.0.0.1:6379: Connection timed out
Interesting part is:
Connection timed out (not refused).
redis-cli -h 127.0.0.1 ping on other workers hosts works as expected (returns PONG).
Docker overlay mash network should expose 6379 port on the local interface on each host, but it looks like something went wrong and I messed up figuring out what exactly.
Other services on the manager host works properly (I can
curl http://localhost:${SERVICE_PORT}/).
Manager host has the same firewall rules as worker hosts (+ additional ports opened)
