Traefik unable to get basic auth working despite using very basic password on docker swarm

Hello.

  1. i not recommend use volumes in docker swarm.
  2. put your files on shared storage for docker swarm (nfs)
    take a look at Traefik 2.5.2 TLS 1.0 1.1 disable

/external/efs/ - AWS EFS service (unix nfs) folder services available on all swarm nodes with same content.
