I had an interesting support case recently that sent me down a few rabbit holes based around OpenSSL. Essentially as a result of an announcement from Google, the provider of a Web Service that a Genero application was calling was making changes to their SSL/TLS certificates used to secure Web Service communication. The Genero developer came to us as they believe they had made the changes to certificates correctly but were getting errors messages referencing certificates. So we started off in the direction of checking certificates, making the web service call with curl and small Genero programs. What we eventually found was that when using their Genero version they would get an error but using a later version of Genero it was OK, and we traced that to the fact their OpenSSL libraries were too old and the Web Service provider was not willing to communicate with them.
