It would be nice if https mirrors were hidden when the current environment doesn?t support them. Alternatively, at least make a distinction between http and https in the mirror listing. They currently just look like duplicates. I think this is a pretty trivial change but would help a lot with usability.

If you update to R-patched, you'll see the difference.  With current
releases of R, you'll see some mirrors twice:  the first one is https,
the second is http.

The other issue you may have is that your system may be configured to
default to a method that doesn't support https.  Try
download.file("https://cran.rstudio.com") and
readLines(url("https://cran.rstudio.com")) to confirm that's not a
problem for you.
