Solved:
I’ve set my modem in bridge mode and now only my router acts as DHCP, it was a bit of a hassle because I set up my pi with a static IP which i forgot to remove. After setting a new static IP and forwarding the 443 port to it, everything is working fine! 
Now it’s time to learn some automation 
EDIT: I think I’m finally getting somewhere, for some reason I can’t ping the TV when on a wired network. The TV is wireless and my Pi is wired, will update this topic with my findings.
EDIT2: Feel free to close this post. I know what the issue is, but it’s going to take some time for me to resolve this. Currently my wired modem acts as a DHCP for the wired network, giving out addresses in the x.x.178.x range. My router is also a DHCP, handing out addresses in the x.x.68.x range, I think this is the reason why some devices can’t connect. Any network specialists out there, feel free to help me
Hi all,
Same as for most of these LG TV topics, I’m a newcomer as well.
At first I started with running Home Assistant in a docker container, but couldn’t get remote access to work so I started over with HassIO on my RaspBerry Pi 4.
When I was running HA in a docker container, I did manage to:
Add the LG WebOs integration and it auto-discovered my LG C1, after of course enabling the Mobile setting on the TV.
However, now I can’t seem to get the pairing to work and I tried a lot of things, this is the issue:
In HA I go to Settings > Integrations > Add Integration and search for the webOS integration.
Next, it asks me for a Host and Name, so I fill in the IP address of the TV:
192.168.68.120
I leave the name empty since I saw this worked for others in other topics.
Now, I get the WebOS TV Pairing option, after pressing submit it spins for a bit and then I get:
Failed to connect, please turn on your TV or check ip address
I am able to ping the TV, I have disabled and restarted all my devices but to no avail.
Any idea what I can do here?
