User can register but can't login anymore once disconnected

Hello,

I opened registrations on twinkaga.in today, with Pleroma updated to commit 88b05aea. Users can register and do everything on their account, but when disconnected, they can't relogin anymore. Here's the log of when they try to relogin.

MastodonFE and PleromaFE have both this error. I tried cleaning and recompiling deps, cleaning and recompiling Pleroma (mix clean, mix compile), I created uuid-ossp in Postgres (because when you make ecto.migrate, there was an error of insufficient privileges when creating the extension), but nothing really explains why it happens. It's the first time it's doing this error, I still can connect to my accounts.
