Need help tracking down Login Error

My log is filled with this and I am not sure where to track down what is causing this.

2020-02-03 16:38:59 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from 172.30.33.3

I am not sure where to even look as as my network is 192.168.20.1/24

I am running HASSIO on vm.
Any other questions you have to help me figure out my issue please let me know.

This might help.

Well I am using the Nginx Proxy Manager add-on but I didn’t do any configuration, I just installed it and its good to go. There doesn’t appear to be any configuration available.

As for the other settings in the configuration I am not using any of them and not sure what I should be using.

Is your configuration.yaml setup? Step 9 here.

I am not sure what I am missing.

http:
  base_url: https://duckdnsgoeshere.duckdns.org
  use_x_forwarded_for: true
  trusted_proxies: localhost

Nginx installed from this https://github.com/hassio-addons/addon-nginx-proxy-manager

Still getting the log in errors.
