I've tried to Google this and the nature of the problem makes things really hard to pin down.  I have an existing site that has been secured via SSL for some time now.  The cert is active and in good standing.  About a month ago I started having issues with random users.  I am unable to determine anything in common with the users who were experiencing this issue, but random users would get a 404 when directed to the login page.  We have a custom login page using the stock login module.  

If the login page is set to secured, random users get 404, if turned off they can get in just fine.  Its on multiple browsers and from multiple ISPs.  Additionally any other page secured generates the same 404, so it isn't just the login module.  I have Smith cart installed on multiple pages and they are secured.  Those too are 404 for these users. Again its not all users and not all ISP's.  If I attempt to login with any of the same users from my computer/house I'm able to log in.  

This site is on DNN 7.2.2.  I have looked at the login pages via Chrome console, and firebug and see nothing in the console.  SSL detects no issues, not even non https content on the page (i've fixed any skin references to http js content and anything else non ssl).  I'm extremely frustrated with this as I have been working on it for weeks looking everywhere and have come up with nothing.  Any help would be greatly appreciated

perhaps it's the poodle issue (http://www.troyhunt.com/2014/10/every...) i.e., your host has disabled one of the vulnerable ssl versions and you have some users with old clients (eg. Internet explorer 6) that no longer work,

Cathal - thanks for the reply. I forgot I posted here about this. After days of troubleshooting, I figured out what the problem was. It was only Chrome browser (updated version) and SSL enabled pages. The issue was called Winshock. Apparently MS released a botched update (kb2992611) and depending on your server and update procedures, getting it fixed is like finding a pot of gold at the end of a rainbow.

We found that if you visited the pages with tls 1.2 disabled, it would load fine. If visiting it without disabling 1.2 it would generate 404. Here is a link to the MS article discussing this. All I can say to everyone else if they are experiencing this is good luck. I still have no clue what I did to fix it. The new update kb3018238 never appeared in the list of installed updates. Then after one final last ditch reboot it did. Tested it again and voila it worked. Hopefully this helps someone else if they fall down this rabbit hole.
