Make MariaDB container accessible via static configuration for Traefik v2

Traefik Traefik v2 (latest)

I tried this configuration via file provider and I want to have the database publicly available on the port 65441:

---
entryPoints:
  some-db:
    address: ':65441'

tcp:
  services:
    some-db:
      loadBalancer:
        servers:
          - address: "some-db:3306"
  routers:
    some-db:
      rule: 'HostSNI(`*`)'
      entrypoints:
        - "some-db"
      service: "some-db"

Traefik and the database container share a docker network but traefik complains with:

level=error msg="In service \"some-db@file\" server \"some-db:3306\": lookup some-db on 127.0.0.11:53: no such host" routerName=some-db@file serviceName=some-db entryPointName=http

And I don't even know why it says entryPointName=http — because this should be a tcp routing. So I guess I have something wrong.
I'm using Docker Swarm in case this makes any difference.

Any advice? Thank you in advance!

Maybe my post can help?

I would suggest that you try IP instead hostname. Are both containers inside same docker network?

tcp:
  services:
    some-db:
      loadBalancer:
        servers:
          - address: "xxx.xxx.xxx.xxx:3306"
