I used to use Traefik but switched to Caddy. I like how easy it is to configure a new reverse proxy for one of my containers. Literally 3 new lines in my Caddyfile, restart the caddy container and away it goes getting certificates etc.
I think it as bug also. I would hope that after the community is retrieved from the remote instance it would automatically display in the search results.
No idea about kbin, sorry. Although I have gotten “Subscribe Pending” when subbing to a few communities - they eventually change to Subscribed.
On your home instance, search for the community you want to sub. Eg: search for http://lemmy.ml/c/test - it will initially say nothing found but after about 10 seconds you should be able to find it in the All Communities list on your home instance. Click on the name of the community to view it, or click subscribe.

I disagree. The mobile web client works fine for me, Jerboa seems clunky and unloved.
