Can't log in to piefed

I was super excited to see that Voyager added experimental support for Piefed. I went a created an account on feddit.online, and tried to log in… and got a connection error. No worries, it’s experimental. That was like 5 months ago and it’s still happening and I’m starting to suspect it’s not going to get better on its own. I use a password manager, and it’s saying “connection error” so I feel like it’s probably not bad credentials? Did I choose a bad instance or is this client-side?
