NPM on a Swarm Cluster does not work well with more than one replica

I'm trying to deploy NPM on a Docker Swarm Cluster. Everything works fine until I add more than one replica to the service.
The last test I did was using a remote MySQL and the /data files on an NFS. I set up a service with 3 replicas and there was no way to get it to be consistent.
My question is: is it possible to deploy an NPM service on a Docker Swarm cluster with more than one replica?
Does anyone have it in production?

This is my latest Stack:

version: '3.8'

services:
nginx-proxy-manager:
image: jc21/nginx-proxy-manager:latest
ports:

• "80:80" # HTTP port
• "81:81" # Management interface port
• "443:443" # HTTPS port
  environment:
  DB_MYSQL_HOST: "ip"
  DB_MYSQL_PORT: "3306"
  DB_MYSQL_USER: "user"
  DB_MYSQL_PASSWORD: "pass"
  DB_MYSQL_NAME: "dbname"
  volumes:
• /mnt/nfs/app:/data
• /mnt/nfs/letsencrypt:/etc/letsencrypt
  networks:
• dts-full-service-network
  deploy:
  replicas: 1
  placement:
  constraints:
• "node.role==worker"

networks:
dts-full-service-network:
external: true

ONLY IF YOU HAVE A REPLICA IT WORKS WELL.
/mnt/nfs/ is an NFS

Start with the Docker Swarm stack shown in the issue and reproduce the behavior with three replicas, remote MySQL, and NFS-backed /data and /etc/letsencrypt volumes. Determine whether multi-replica deployment is supported and document or resolve the consistency problem, with production guidance as the completion criterion.
