SSL handshake fails when SPDY profile is attached.


SSL handshake or other connection failure.


This occurs when the following conditions are met: -- Client (i.e., Chrome for Android) attempts to use SPDY protocol using Next Protocol Negotiation (NPN) during SSL handshake. -- BIG-IP system has a Cavium Nitrox card.


Remove SPDY profile.

Fix Information

SSL handshake now completes successfully when a SPDY profile is attached when Next Protocol Negotiation (NPN) is detected on a BIG-IP system with a Cavium Nitrox accelerator.
