The DNS-01 challenge can be used to generate a wildcard by creating the requested dns record in your public dns zone, then you can use that cert for internal servers/dns. With certain dns providers it can even be automated.

While this is a great writeup on Lemmy instances, the thread was specifically about Mastodon and it’s numerous forks. I believe they use the same tech but are vastly different things. The instance I found wasn’t quite Mastodon apparently, even though it works very similar and the app designed to connect to a Mastodon instance wouldn’t connect to it.

I’ve been looking for a new instance to join due to various reasons. Ended up setting up and account somewhere and spending 2 hours manually copying over various settings only to find my Moshidon client won’t even connect with that new instance. Normal people are just going to quit when that happens.

Rhem is a myst-like which will probably require multiple journals.
