SSL/TLS secured HTTP communication requires that the browser know exactly who owns the server being accessed. They do this by means of a certificate issued and signed by a central authority. For a server to gain a certificate proving it's identity, it must first prove that it has control over the website it claims to represent.
General Bytes does not own nor does it control your website. General Bytes cannot therefor gain a publicly verifiable certificate to install on your server. This does NOT make your communications less secure, it just means that you must manually approve access to the web page. You will receive a "self-signed" certificate. It verifies that every time (in the future) that you visit your site, no one is "in the middle".
Your browser is merely doing what you rely upon it doing - and admirably so.
