Login attempt failed 172.30.32.2

HA is denying itself access - Login attempt or request with invalid authentication from 172.30.32.2

I had been using ip_ban_enabled and login_attempts_threshold: but with the above login issue it was causing HA to ban it’s own IP address. I had read a threat which said these issues have been resolved in a later version of HA, so I upgraded to (0.113.3), however it still persists.

I’m not sure if it is related but I see this in the log files, but it may just be due to the above login failure.
