[Fixed] Why am I receiving this error on opening a given instance?

I love that Liftoff allows me to see an entire instance and its posts on different communities, but I'm having issues with the lemmy.eco.br instance, specifically. I'm subscribed to a community in it and I can see it just fine, but if I click the instance I receive the following:

The same error appears when I click my communities button right now (I believe it started after updating the app).

Also, going on settings > account > add instance, I receive "instance not found".

Edit: it is working after updating
