HassIo + DuckDNS Install can't login

I installed duckdns on my hassio.
I confirmed via the logs that I got a key and a certificate.
Updated the http part in configuration.yaml
I also did the port forwarding.
when I open a webbrowser and try opening Home Assistant via my duckdns account it goes to the Home Assistant Login Screen, then waits there and suddenly says “Something went wrong” in a red text.
Please help!

I just found these messages in the logs:
2018-10-25 20:13:18 ERROR (MainThread) [homeassistant.loader] Unable to find component ssl_key
2018-10-25 20:13:18 ERROR (MainThread) [homeassistant.setup] Setup failed for ssl_key: Component not found.
2018-10-25 20:13:19 ERROR (MainThread) [homeassistant.loader] Unable to find component ssl_certificate

2018-10-25 20:13:19 ERROR (MainThread) [homeassistant.loader] Unable to find component base_url

And now it says that the SSL handshake failed
–> Error doing job: SSL handshake failed
