No HTTPS available for plugins.drone.io

Hi. I’m new to drone.io, but having HTTPS enforced in my Firefox I have noticed that plugins.drone.io is not available via HTTPS:

$ curl https://plugins.drone.io/
curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to plugins.drone.io:443 

Maybe it’s just an outage, but assuming the site is only available via plain HTTP, it casts a shadow over the plugin ecosystem (even though plugins could possibly be fetched via secure connection to the Docker registry).
