Hello, have Home Assistant 2022.9.4. Somewhere around version 2022.8 version I noticed strange problem. I can login from my local network. But not from outside (via myowndomain:8123). I run on http only. It shows login but after I will use credentials it shows bad username or password. I checked multiple times all is right written.
I use TOTP and everything worked before without any problem. Log is empty.
Any idea please? Thanks.
Have you checked if the user settings are set in a way that the user is allowed to logon from an external network?
Yes I have, everything is and was set right…
Tried to clear the browsers cache ?
And what happens when you use the anonymous mode of the browser or browser from some other device? (which is basically the same as using anonymous mode)
Is it the uid/pwd that fails, or the TOTP?
The answer probably is yes, but are all system times correct?
Is your Public IP changed and does that affect your router/firewall config?
Do you use a reverse proxy?
Is it the uid/pwd that fails, or the TOTP? uid/pwd fails. TOTP doesn´t shows.
The answer probably is yes, but are all system times correct? Yes
Is your Public IP changed and does that affect your router/firewall config? No. Everything is OK.
Do you use a reverse proxy? No
Well…maybe one thing. I tried to install reverse (few weeks ago) proxy using Nginx and Nginx proxy manager. I installed both but was not able to get it work. So I uninstalled. Maybe this is the point (I can´t remember exaxctly) when login stopped working. So maybe this could be some problem. Maybe it causes some setting change somewhere… but where to search for?
I never used the reverse-proxy of HA, so hopefully someone else has knowledge about it.
Have you tried the remote access using your IP instead of the domain name?
Holly s*** - my mystake. Sorry. I made domain name for my friend and forgot it. Now I thought his domain name is mine… So I tried to log into his instance of HASS.
Sorry people.
Always check your IP´s 
Problem solved, thanks for reporting back
