I have Portainer successfully configured with oauth and immich/portainer and voidauth are within the same reverseproxy and docker swarm environment.

I tried also the Auth Methods post/basic and none.

The Immich traedfik swarm compose label are

traefik.enable: 1
traefik.swarm.network: cloud-public
## HTTP Routers
traefik.http.routers.immich.entrypoints: web
traefik.http.routers.immich.rule: Host(`immich.mydomain.com`)
## Middlewares
traefik.http.routers.immich.middlewares: voidauth-middle@swarm
## HTTP Services
traefik.http.routers.immich.service: immich
traefik.http.services.immich.loadbalancer.server.port: 2283

The portainer traedfik swarm compose label are

traefik.enable: 1
traefik.swarm.network: cloud-public
# define traefik dashboard router and service
traefik.http.routers.portainer.rule: Host(`portainer.mydomain.com`)
traefik.http.routers.portainer.service: portainer-svc
traefik.http.routers.portainer.entrypoints: web
traefik.http.routers.portainer.middlewares: chain-no-auth@file
traefik.http.services.portainer-svc.loadbalancer.server.port: 9000
traefik.http.services.portainer-svc.loadbalancer.passhostheader: 1

The main difference is the middleware?
