We provide Internet to customers using the network setup like this. We have Bandwidth Manager installed on a server with a LAN and WAN adapter.
When customers are behind on their bill, we want to redirect them to a notification page. It used to work using the mapping to "http://ourwebsite.net" but when browsers no longer support unsecure HTTP protocol, that stopped working. I've been unable to make it work with "https://ourwebsite.net". I've also tried to host the page on the same server and use "redirect to local port", but that hasn't worked either.
Let me know what information I can provide to enable you to help me make this work. I could even set up a temporary account for you to login to the server. I've attached a backup [link] in case it helps.
Thank you in advance.
