Minio install behind Traefik - docker-compose

Question

I had the previous version (from last yr) of minio running well behind traefik and on portainer with no issues. I attempted an upgrade 4 days ago to the new version and it's been downhill since then. I get the login page but it won't accept credentials; Error:
{"code":500,"detailedMessage":"Post \"https://storage.example.com/\": dial tcp <ip>:443: i/o timeout","message":"invalid Login"}
I suspect it has something to do with the TLS certificate.
Below is my compose file, I've generated the certs as required; any assistance is is welcomed:
minio:
image: minio/minio
container_name: minio
restart: unless-stopped
command: server /data --certs-dir "./minio-data/certs" --address ":9000" --console-address ":9001"
networks:
- traefik-proxy2
expose:
- "9000"
- "9001"
volumes:
- ./minio-data:/data
environment:
- "MINIO_ROOT_USER=love"
- "MINIO_ROOT_PASSWORD=love1234"
- "MINIO_BROWSER_REDIRECT_URL=https://stash.example.com"
- "MINIO_SERVER_URL=https://storage.example.com"
labels:
- "traefik.enable=true"
- "traefik.http.services.minio.loadbalancer.server.port=9000"
- "traefik.http.routers.minio.rule=Host(`storage.example.com`)"
- "traefik.http.middlewares.minio-https-redirect.redirectscheme.scheme=https"
- "traefik.http.routers.minio.middlewares=minio-https-redirect"
- "traefik.http.routers.minio.entrypoints=https"
- "traefik.http.routers.minio.service=minio"
- "traefik.http.routers.minio.tls=true"
- "traefik.http.routers.minio.tls.certresolver=http"
- "traefik.http.services.minio-console.loadbalancer.server.port=9001"
- "traefik.http.routers.minio-console.rule=Host(`stash.example.com`)"

Answer 1

I was getting the same Invalid Login error: Post "http://minio.localhost/": dial tcp: lookup minio.localhost on 127.0.0.11:53: no such host.
The following docker-compose.yml works. The solution is NOT to use MINIO_DOMAIN or MINIO_SERVER_URL. See # comments at environment: variables.
version: "3.3"
services:
minio:
# Please use fixed versions :D
image: minio/minio:RELEASE.2021-10-06T23-36-31Z
networks:
- traefik-proxy2
volumes:
- minio-data:/data
command:
- server
- /data
- --console-address
- ":9001"
environment:
- MINIO_ROOT_USER=love
- MINIO_ROOT_PASSWORD=love1234
# Do NOT use MINIO_DOMAIN or MINIO_SERVER_URL with Traefik.
# All Routing is done by Traefik, just tell minio where to redirect to.
- MINIO_BROWSER_REDIRECT_URL=http://stash.localhost
