Multiple hosts in traefik.http.routers.app.rule does not work in v3?

Traefik Traefik v3 (latest)
1

Hi.
My docker container running Traefik has been upgraded to v3, and one of my containers behind it has stopped working.

Traefik gives me this error:

error while adding rule Host("piwigo.domain.tld", "album.domain.tld", "foto.domain.tld"): error while adding rule Host: unexpected number of parameters; got 3, expected one of [1]

The label in question is: traefik.http.routers.app.rule
And it looks like this:

Host("piwigo.domain.tld", "album.domain.tld", "foto.domain.tld")

This was no problem in Traefik v2, but it is a problem in v3 apparently

How is the syntax supposed to look like for this in Traefik v3?

Thanks

Only one domain per Host() in v3, use:

.rule=Host() || Host()

Works like a charm!

Thanks
