Login attempt failed - network issue

Hallo, I receive this message from HA very often, randomly, I do not understand cause.

Login attempt failed
Login attempt or request with invalid authentication from myfastgate (192.168.1.1). See the log for details.

And in log I have:

2021-02-26 15:12:52 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from myfastgate (192.168.1.1).

Someone can help me?
Thank you

I have the same and learnt to live with it… I think it has something to do with remaining open sessions.

Hi there!

Similar problem here, same error message but different IP address.
In my case, I’m accessing my HA from the Internet with port forwarding.

Is there something that can be cleared on the config?
[homeassistant.components.http.ban] it seems like there is some kind of ban.

I get this after force closing the mobile app, even when on the same network as my HA server.

Same here

There so many topics opened on this problem in the forum in 2017 … 2021 without any valuable proposed solution unless I missed it

Totally randomly. Different devices, various times - no pattern.

No root cause → no solution?
