Adding SSL to Site Issue

The domain is registered on GoDaddy. The hosting is also on GoDaddy. It's a Wordpress site. SEO IS VERY IMPORTANT so this needs to be done right. So here's the deal... The client runs their site through a proxy ([login to view URL]) It's almost as if they're hosted by two different companies. The companies both have their own SSL Certificates. We can get it switched and working, but it's not 100% because links break on the site. If the entire site is switched to HTTPS using recommended methods you'll be stuck in a redirect loop. If you mess with the 2 different settings and clear cache on sucuri's side you'll still wind up with the same issue. Somewhere something isn't switching over properly. 1. We NEED to make sure that if someone visits the http:// it kicks them to https:// 2. We WANT canonical links to point to the https version 3. We would like this to be worked on during off-hours during the American work day (5:00 PM - 6:00 AM) Additional notes Probably unrelated from this issue, but we did notice the new plugin "GoDaddy Pro Sites Worker" that wasn't there before. We don't know if that's just something that GoDaddy installs now or if they are using ManageWP. We can't log into that or Pro sites/ManageWP, but again, we don't know if this plugin is just something GoDaddy installs to handle a few of their things on their end or if someone there now uses that. The site itself is accessible over HTTPS and has been for awhile, but the WordPress install loads resources and stuff over the non-HTTPS version which is why it looks broken--Chrome and other browsers will block non-secure resources if you're visiting an HTTPS website. If you switch it you'll get the redirect loops issue though.
