Adapted from my answer at How to ignore 'Certificate Verify Failed' error in perl?: 
use IO::Socket::SSL qw();
use LWP::UserAgent qw();
my $ua = LWP::UserAgent->new(ssl_opts => {
    SSL_verify_mode => IO::Socket::SSL::SSL_VERIFY_NONE,
    verify_hostname => 0, # this key is likely going to be removed in 
+future LWP >6.04
});

Then set the ua attribute on the Frontier::Client instance.
