Very well done, although it starts slow (thought it was going to be just the initial simple text).
Like others I had a problem with the page cert (GitHub cert). Going to http://strml.net fixed it on the redirect to https://www.strml.net (which is using a Letsencrypt cert for www.strml.net)
Love that adventured... bit long, but good.
I am getting:
Error code: SSL_ERROR_BAD_CERT_DOMAIN
This one is really cool! Never seen anything like this before.
