Test 'https_proxy.t' fails on windows 10

While installing the module through cpan, the 'https_proxy.t' testcase is failing with error - unexpected response: 500 SSL upgrade failed: SSL connect attempt failed error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

The error is similar to https://github.com/libwww-perl/LWP-Protocol-https/issues/58. Since the test case is different and different OS hence creating this ticket. Installing it on personal PC hence no corporate firewall.

Perl version - Strawberry Perl 5.30.1 built for MSWin32-x64-multi-thread
LWP::UserAgent - 6.42
