Edit: It was a very dumb thing, I was typing "hostname" as indicated in the Kodi wiki guide instead of "localhost". About the local ip route, I don't know why but it was a different address than the one i used to acces my router configuration.
I just installed TVheadend into my Raspberry Pi 3 (raspbianstretch), through the mpmc repository.
Everything went presumably fine, registered my user and password into the terminal pseudo gui and now when I proceed to configure it into Chromium (also tried Chrome into another computer adding my IP), I just get "This site can’t be reached
hostname’s server DNS address could not be found."
Probably is some stupid mistake but I'm really a newb into all this networking stuff.
Also tried it with other ports (--htps_port and --http_port), with daemonizing (-u user and -f I think) and without daemonizing. I must say that in this later option always finds problems connecting to the ports in the terminal emulator (and in the plain terminal also), but when I do change them to other ports i also find the same problem connecting to them, but none in the terminal (port lines appear green).
I must also mention than sometimes when I first type the Tvheadend in the terminal, it appears as a second process (TVheadend #2), so maybe it is running automatically when i start the raspberry? This does not happen always. And I never find two instances of tvheadend in the task manager.
Thanks for your help.
PS: Forgot to mention, I always find this line marked red "2018-05-22 12:51:15.957 [ ERROR] access: No access entries loaded"
