Gotcha thanks for the info! It looks like I would be fine with ocis or opencloud, but since my main use case and pain points are with document editing which is collabora, it probably wouldn’t change much besides simplifying the docker setup (I had to make a gross pile of nginx config stuff pieced together from many forum help posts to get the nextcloud fpm container to work smoothly). But it already works so unless it breaks there’s little incentive for me to change.
I use a .dev and it just works with letsencrypt. I don’t do anything special with wildcards, I just let traefik request a cert for every subdomain I use and it works. I use the tls challenge which works on port 443, so I don’t think HSTS or port 80 matters, but I still forwarded port 80 it so I can serve an http->https redirect since stuff like curl and probably other tools might not know about HSTS.
