Can't access Home Assistant from other browsers

I have a problem with accessing Home Assistant UI (running Hassio) from other computers/tablets than from where I set it up and I can’t seem to find the root cause of it.

What works:

  • Accessing https//192.168.10.122:8123 and logging in with username and password from the stationary computer I have

What doesn’t work:

  • Accessing https//192.168.10.122:8123 and logging in with username and password from any tablet, mobile phone etc that is on the same network.
  • I get to the login screen, enters the same username and password and get the error message “Unable to connect to Home Assistant”. The log shows

2018-12-24 11:57:12 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from 192.168.10.179

I have duckdns enabled and configured on the Hassio.
I have the RaspberryPI that I am running this on in a basement room and including/excluding z-wave components is hard when you are not in the same room…

I would imagine that you do not have any encryption on your local network and what you actually need is just http

http//192.168.10.122:8123

Your computer has been banned for too many bad logins. Edit the ip_bans file in your config directory. (I think that is the filename)

I thought so, but there is no ip_bans in the config directory as I haven’t configured ip_bans…

https is necessary to access, so can’t access without.
