Have a look here for information in running a Lemmy instance.

Sorry - I didn't run into any issues with user creation. Can you provide some context to this? What are you seeing in terms of errors/behaviour?

Not sure of the issue, but take a look here to see if there is something that can help.

Yeah from memory (was a while ago), Traefik hooks into the docker socket to auto-discover containers that have a specific label? Might not be remembering that correctly.

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

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.

Maybe thumbnails?
