As previously announced, the Lucity Mobile 2.0 application for iOS will require SSL with TLS 1.2 starting next week. In addition, SSL must be configured to support (perfect) forward secrecy using the Elliptic Curve Diffie-Hellman (ECDHE) key exchange. This requires cipher suites installed on Windows Server to support this key exchange. The order of the cipher suites will also affect whether perfect forward secrecy is supported.
If you have any questions or need help figuring out whether your servers will support the new requirements, please contact Lucity Support.
