This is a questions regarding moving to your https. I did this with my website (www.missjessicawoodvideos.co.uk) but then CCBill couldn’t create passwords properly. They got this error: "Failed (Did not receive valid response for jpost local ( <meta http-equiv=“Conten))”.
They seemed to think their IPs were being blocked:
64.38.194.13
131.153.40.106
Have you heard of anything like this happening? As when I turned off Lets Encrypt certificate it worked again.
I want to use the SSL but make my members site work as well. Any help would be amazing or if you need more info let me know.
It is difficult to be certain with such minimal information…
But it seems that the biggest (and most likely) culprit is Apache. {Notorious for running at any/all costs, it tends to allow/overlook “errors” that would sometimes stop a horse.]
I would suggest try moving your site to an nginx implementation or simply add an nginx proxy to your existing system and go from there.
[presuming the CCBill program runs on the same system]
It would be helpful to get some specific logs, ideally from both ends. Do you think CCBill can give a more detailed error message and a more detailed description of what URL they were trying to access? And does your own web site have logs that you can access?
