Picade Hat setup not working

Hello,
I’m having trouble setting up my picade.
The code to install the software curl -sS https://get.pimoroni.com/picadehat | bash is not working, I’m getting an error with the SSL Certificate?

Try it over straight http, so:

curl -sS http://get.pimoroni.com/picadehat | bash

Thanks for the reply Matt, I have tried it over straight http and I’ve tried it over non secure -k
Still not connecting to the link?
