It's not Let's Encrypt. Hiawatha-proxy just doesn't work on https. http works perfectly.
In Kolox cp, I now have these unchecked.
Force Redirect 'domain.com' To '
www.domain.com'
Force Redirect 'http' To 'https'
It works perfectly with http. When visit https that when the problem occur.
How can I get it to work with https?
