AOL Mail account Error

My aol email account will not retrieve new emails. It’s says “Cannot get mail. No password provided for emailaddress@aol.com” please go to mail account settings and enter a password. I’ve done that several times on my iPhone and iPad. Also reset network settings. Both are updated to new iOS. Deleted aol mail from accounts on iPad first and now I cannot add it back in mail accounts. Still not working on iPhone. See attached photo for the pop up I keep getting.
