Cannot access HA after installing DucksDNS (Edit: Post #3 Cannot access domain from outside LAN)

Hi guys,

I just set up Home Assistant on a Raspberry Pi4 and everything was working great (straight of using the IOS from HA). But after installing the DucksDNS I cannot access the Pi/HA at all anymore.

I followed these instructions:

I have Google Mesh and the port forwarded like this:

In between the wall and the Google Mesh I have an Arris router. I can’t find any way to forward ports in it, nor do I know if it’s necessary, but I’ve done this:

I know I made one mistake when entering in the domain in the config of DuckDNS, I had the “duckdns.org”, I’ve later seen that I shouldn’t.

I’ve tried to access it both from inside my lan and outside it.

I feel kind of handcuffed since I can’t access anything. Anyone got any ideas what I can do? Any other way to access it? Should I just pull the SD card and format it and start over? Or can I reset the DuckDNS configurations by connecting the Pie to a screen and keyboard?

Any help anyone might have would be greatly appreciated!

I am sorry for taking your time with such a simple question, but I am kind of lost…

It seems like I solved this problem by just doing this with the port forwarding:

So I can now access HA using the ip-address from inside my LAN. But I still cannot access from the outside using my domain name through DuckDNS.

These are my settings:


When I access ha from inside my network, it says that my certificate is invalid, I have no idea why.

Any help, thoughts, questions or tips would be greatly appreciated!
