This is not exactly channel for Traefik (it seems they don’t have Slack, Gitter, etc…?), but would anyone happen to know about best practices regarding Traefik ingresses? My traffic from outside mostly comes in HTTP/2, but it seems that the services receive it in HTTP/1.1. Is there any performance impact in this, or would it be better to have Traefik<->Service communication also in HTTP/2 (or h2c)?

There used to be a Traefik Slack but now it's community.traefik.io

Yea, that is not very convenient for discussion.
