The problem is with your website itself. When I look at the Source Code of your website you have both http and https links in your Source Code. All links MUST be https and you cannot have any http links at all otherwise things will never work correctly such as redirects or rewriting. To view the Source Code of your website – right mouse click on your website home page and click View Source or a similar command. You will see http links in your Source Code (see below). I can only tell you what needs to be fixed and not how to fix it.
