Problems setting up ssl certificate

[Nephylim]

Hi There,
my Domoticz is running flawlessly as a http server.
I however decided it was time to switch to ssl encryption.

Therefore I tried creating a ssl certificate using the following instructions

http://www.domoticz.com/wiki/Native_sec ... ts_Encrypt

When trying to validate the certificate i end up with a socket error errno13 permission denied.


I also tried the secon method to create and validate in one go with
sudo ~ ./letsencrypt certonly --webroot --email <your email> -d <your domain name> -w <user home>/domoticz/www/

in that case I get an error:
Could not connect to (mydomain)

The Domain is working without a problem. The Ports 80/443/8080 are forwarded to the raspberryand I am able to connect to port 8080 with http and port 443 with https.

I don not understand why I have to forward port 80, cause nothing is listening on that Port.
any Idea what I am doing wrong?
