Erroneous "All packages are up to date" behind enterprise self-signed cert

When behind a corporate firewall with self signed certificate and download.file.method == "libcurl", connection to CRAN mirror fails:

Warning: unable to access index for repository https://cran.rstudio.com/src/contrib:
  cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES'

This is tied to R's changes to libcurl and is resolved in 4.2.2 (I believe).

THE ISSUE: However, under R 4.2.1 and with a failure to connect securely to a CRAN mirror, RStudio IDE's "Packages pane > Update" reports "All packages are up to date".

When unable to connect to CRAN, RStudio should not report everything being up to date.
