After upgrading from php:8.3-fpm-nginx-v3.3.0 to php:8.3-fpm-nginx-v3.4.x Traefik not working

[tjura]

I have a setup with Traefik. Everything worked fine on version 3.3.0, but since 3.4.x, this setup stopped working. Does anyone have an idea why? In the Traefik dashboard, under the routers section in version 3.4.x, nothing shows up—it’s almost as if Traefik can’t see the labels at all. Version 3.3.0 works fine with the same config; I just checked it.

        labels:
            - 'traefik.enable=true'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api.entrypoints=http'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api.rule=HostRegexp(`${DOMAIN}`)'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-www.entrypoints=http'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-www.rule=HostRegexp(`www.${DOMAIN}`)'
            - 'traefik.http.middlewares.traefik-https-redirect.redirectscheme.scheme=https'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api.middlewares=traefik-https-redirect'
            - 'traefik.http.services.${COMPOSE_PROJECT_NAME}_api-secure.loadbalancer.server.port=8080'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.entrypoints=https'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.service=${COMPOSE_PROJECT_NAME}_api-secure'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.rule=HostRegexp(`${DOMAIN}`,`{subdomain:[a-z]+}.${DOMAIN}`)'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.priority=2'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.tls=true'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.tls.certresolver=${CERT_RESOLVER}'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.tls.domains[0].main=${DOMAIN}'
            - 'traefik.http.routers.${COMPOSE_PROJECT_NAME}_api-secure.tls.domains[0].sans=*.${DOMAIN}'

Sorry for the delayed reply. My inbox went bonkers these last few weeks 🤪

Are you using health checks at all?

I had issues the other day and I needed to fix this because I went from HTTP to HTTPS
