I can't log into pd in jerboa?

So, it used to work just fine. Then jerboa became basically unusable due to some bug. That was a few weeks ago. I saw an update was available, so I thought to give it another try. It's much more stable after the update, and my lemmy.one account works just fine. But when I try to log in with this account on jerboa, I get an incorrect login error. I set the instance to "programming.dev" and I know I used the right credentials because my password manager filled them in, just like it does in the browser.

Any ideas on a cause or fix? It might be a jerboa issue but I don't get why it seems to only impact this instance.
