I recently setup Traefik 2.x to front a self-hosted Docker Registry, with automated Let's Encrypt renewals - I found the config to be really unintuitive and confusing! It feels like an awful lot of really finicky config for such a simply setup. Next time I'll try something else.
Caddy v2 seems to be doing something right although I don't think it comes with the same number of features out of the box. Plus it's more of http reverse proxy.
