Unable to start duckdns

I am trying to setup remote access using the speak to the geek video, but have fallen at the first hurdle.
I have created a duckdns.org domain and installed duckdns add-on. But when I fill in the config and try to start the add-on I just get the spinning circle for quite a while and it doesn’t start.
this is the log
