Probably, but I cannot reproduce it.
If it is, you need to file a rt.cpan.org ticket for this,
with some wireshark loggings and the exact request.

$ lwp-request https://www.geocaching.com/
501 Protocol scheme 'https' is not supported (LWP::Protocol::https not
installed)

... (built and installed SULLR/IO-Socket-SSL-1.77.tar.gz,
