[iOS] [RESOLVED] Issue: Logging into lemmy.world gives "incorrect_login" on this account

As title says, no matter how many times I try, or manually type password, I cannot seem to log in into this account from iOS app... Anyone got idea as to why?

In server name I type "lemmy.world" and in username I type my username from here... and yet, "incorrect_login" pops up every time. I tried manually typing pw multiple times and also using 1Password and yet nothing works.
