User unable to login

I’ve encountered a strange issue with home assistant where 1 user can’t login. No issues with other uses logging in.
Configuration doesn’t have ip ban setup, but it looks like a user ban. I just don’t know how to remove it.

Environment:
python venv
Rasp pi 4
Running through nginx reverse proxy
Version: Home Assistant 2020.12.1

Configuration.yaml

http:
  use_x_forwarded_for: true
  trusted_proxies: 127.0.0.1

Error on login:

Logger: aiohttp.server
Source: components/http/ban.py:102
First occurred: 7:26:50 PM (3 occurrences)
Last logged: 7:29:25 PM
