21 hours ago I have the exact same problem with the same setup:
- have users_external enabled with IMAP backend (Mailu, in my case)
- have a user authenticated by this backend (I have all users authenticated via this backend)
- have NC app with that user's creds logged in (in my case not via QR code, just entered username and password)
- turn off IMAP backend for a few minutes (happened in my case during an update of the imap server, just a few moments)
- app says "Wrong username or password"
- turn the backend back on
- app still says "Wrong username or password
The odd thing is that other users with the same backend and the same nextcloud app are not affected. My hypothesis is that this only affects clients which happened to try to authenticate the moment the imap server was down.

Steps to reproduce
users_externalenabled with IMAP backendExpected behaviour
App should stop nagging about wrong username and password and just work as it did before since nothing changed. Other apps not using the NC account provided by NC app don't have this issue (Talk, browser extensions, etc) but apps using the NC-provided account fail to connect, too.
Actual behaviour
Instead of restoring to working condition transparently the app remains convinced that the stored credentials are wrong and forces a new login, i.e. the login screen is displayed no matter what I try to do, including force-close and phone reboot.
I have to find a computer, log in through a browser and generate a new app token/QR code unnecessarily.
