Why does the old web server even need HTTPS? Have I missed a memo that HTTP is going away?
If you're not sending anything private (ie just the contents of the website are being delivered) there isn't really any need for HTTPS, so leave that old HTTPD server running HTTP.
But, if you want your stuff encrypted, you can't rely on old versions of HTTPS so you have to use something more modern.
Also, if you want your transmissions to be secure, you probably shouldn't be relying on hardware/software that has passed EoL ages ago too.

In those 5 years, HTTPS has gone from being the minority of traffic to being ~90% of the connections observed by most Chrome clients (scroll down a few graphs for the Chrome-observed one):

That doesn't mean that HTTP is banned, but given the magnitude of the change and the size of the web, I think it's fair to say that it's being deprecated.
More practically, anyone who wanted to build a product (or a government process) on intercepting or modifying people's unencrypted web traffic would find their dataset to be an order of magnitude smaller, and orders of magnitude less useful (since so much of the remaining HTTP traffic is in the long tail of small/older sites).
Pretty sure that’s mostly a US problem, I haven’t heard of any other first world country where this regularly happens. You should probably work on fixing the problem instead of requiring everyone to accommodate you.
