IMAP Error Message for Apple Mail on iOS 18.2

I keep getting an IMAP error message when I try to get my Email Iv deleted the account and reinstalled it and done all that it says on the Internet to do but still can’t get my email on the Apple mail app in know my password works as I can access my mail on line & my password is correct?? This as only happened since I updated to 18.1 just updated to 18.2 and it still doesn’t work anymore suggestions
