What was an HTTP request is now an HTTPS request, which is why you see port 443 referenced, and the prefix changed.? This change happened some time ago, I think it was a couple years.
There are several workarounds, depending on your linux sophistication.? In essence they all work thru a local HTTP server to appear to XEPHEM appropriately, and actually passthru a fetch via HTTPS.? Thus all of the pita HTTPS effort moves into an external program.
If you just want images, 'wget' works fine.? If you want to complain, ask SOHO why a fully secure transaction is needed to fetch an image.
