Well I've made some progress. It turns out I was missing a forward slash in my jenkins URL setting (there really should be a syntax check there IMHO)
So now it no longer reports that the reverse proxy is not working. But launching a slave fails in both cases. In windows, from the browser, I am getting an exception FailedDownloadException: Unabvle to load resource: https://mydomain.com/jenkins/jnlp.jars/remoting.jar and in OSX, from the command line I get Failing to obtain https://mydomain.com/jenkins/computer/iMac/slave-agent.jnlp?encrypt=true javas.net.ssl.SSProtocolException: handshake alert: unrecognized_name -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
