Ah, makes sense. Yeah, these days with http2 it's actually faster to use HTTPS most of the time

Now that the SSL is fixed I see you are doing something unusual: You are redirecting https -> http. Is that intentional? Most sites do the opposite these days.

Just wanted to let you know that the main website is failing SSL checks. The primary certificate is fine, but a few certs in the trust chain expired at the end of May. I believe you should be able to download a new cert bundle for free when that kind of thing happens.

You can use this to validate your SSL chain is working properly:

Also, you have a few ciphers/protocols enabled that are on the less secure side. Might be good to tighten up the SSL settings. Here's a handy site for generating the SSL config block for various web servers:
