Unable to pass traffic through Pulse Secure Desktop Client on IOS after upgrade to 188.8.131.52105 when the following critera is met:
- The PPS or PCS appliance is configured with AES or 3DES with 128 bit or 168 bit Cipher Suite (System > Configuration > Security > SSL options).
- The Pulse Secure Desktop Client on iOS connects is connected with SSL Transport mode (Users > Resource Policies > VPN Tunneling > Connection Profiles)
NOTE: If DES is configured, then Pulse Secure Desktop Client may not be able to connect at all.
NOTE: This issue may still occur if the Connection Profile is configured to use ESP if the Pulse Secure Desktop Client fallbacks from ESP to SSL. This can happen if the client is unable to make an initial connection to ESP or remain connected using ESP on UDP port 4500.
