Can't access HASS.IO in any way after installing DuckDNS

Here’s what I did in order to install DuckDNS:

      1. Created DuckDNS account/sub-domain
      2. Installed and activated DuckDNS addon through hass.io-panel after I edited the config
      3. Edited configuration.yaml with:
          base_url: https://heremydomain.duckdns.org:8123
          ssl_certificate: /ssl/fullchain.pem
          ssl_key: /ssl/privkey.pem
      4. Forwared:
          service port 443 internal port 8123 to RPi3 ip
          service port 80 internal port 80 to RPi3 ip

Now, I am unable to access hass.io through hassio.local, https://heremydomain.duckdns.org:8123 or myraspberrypiIP:8123. Samba and my SSH connection stopped working.
I can ping my pi locally and when I ping heremydomain.duckdns. org it returns my ip.
Also, hassio.local:3218 (configurator addon) works for some reason.

It would be truly appreciated if anybody could help.
Thanks!

That was lucky!

Try specifying the base URL without https:// or a port. Then restart.

Didn’t seem to change anything when I tried:
http:
base_url: momanhome.duckdns.org
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

I have found my log file though:
2018-12-10 21:11:05 ERROR (MainThread) [homeassistant.config] Invalid config for [http]: not a file for dictionary value @ data[‘http’][‘ssl_certificate’]. Got ‘/ssl/fullchain.pem’
not a file for dictionary value @ data[‘http’][‘ssl_key’]. Got ‘/ssl/privkey.pem’. (See /config/configuration.yaml, line 16). Please check the docs at https://home-assistant.io/components/http/

My certificate and key are really in the ssl file. I don’t know if I can access the addon’s config to disable ssl but it would probably work without it.
