😥. I will fix it! I think because we are still going via nginx, it's still has to pass the go-away challenges, which it must be failing and thats why...
Annnd, as we just moved I also only have key access to the server and I made all new keys and don't have one on my other devices yet. (A classic)
Edit: nope, it's now attempting to connect over https to the container... I think I'll need to write a proper patch for it to allow for a override.
It also looks dead in the water/feature complete. So I've moved to FSFs container. (https://github.com/Fedihosting-Foundation-Forks/mlmym).
If I end up making a patch I'll upstream. (I'm surprised LW hasn't made one already)
