Hello, I have this hostname: mail.openmbox.net when access it as http, it will be rewrited to https (rewrite and certs setup by certbot automatically). this works fine in chrome browser. but when I access http://mail.openmbox.net in firefox, it will show the default site. That's to say, http://mail.openmbox.net/ works correctly on chrome (show the correct site and rewrite to https). but it shows the default site (ubuntu default html) on firefox as you can test it as well. I am totally confused. can you help? Thanks.
