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.
