in reply to Working with Confluence and LWP

You could try setting the "PERL_LWP_SSL_VERIFY_HOSTNAME" environment variable - if that is set to 0 then LWP::UserAgent will honour it. If that doesn't work for you then you could get your hands dirty a little bit and add a couple of lines to the Confluence::Client::XMLRPC source. Also note that in the docs for that module it says that the XML API will be deprecated in favour of a REST one, no dates are given though.
