Global Collect temporarily deployed an SSL change which broke the orphan slayer, here's some text from their latest update:

Ongoing monitoring of our production environment have highlighted that additional changes related to RC4 cipher disabling / tomcat upgrade may influence specific customer behaviour in the interaction with our platform. As such, we decided to postpone the introduction of the new enhancements in order to safeguard day to day processing of our clients.

We need to make the fixes on our end to be compatible with their new changes when they eventually are deployed for real. Is this ready to test on GC's staging server?
