Hi everyone,
I was able to follow the instruction on this page: Google Assistant - Home Assistant, including setting up an external hostname and SSL certificate. Let’s Encrypt add-on has no error and my Home Assistant received a SSL certificate. My external IP address is correct since Let’s Encrypt requires port 80 in order to generate a SSL certificate.
However, when I tried to add my newly created [test] xxx device, my browser would say “could not establish a secure connection”. What am I missing?
Thanks.
