Setup HTTPS using LetsEncrypt
Title says it all. Would be great to setup SSL/TLS and you can easily setup to auto-renew certs fairly easily. Better security on the web is always good.
https://crates.co/ works for us – are you having an issue accessing the site via https?

Was unaware that you had https setup as the site doesn't redirect to it when coming in from http.
