When I upgraded to MacOS Sierra, my Pulse client no longer worked. I then upgraded to release 5.2. I have two identical SRX 240 firewalls. One will allow me to connect and the VPN works great. When I try to connect to the other I get "Connection Error No firewall configuration available. (Error:1466)"
No configurations have changed, only the Pulse client. I see not IKE attempts in my SRX logs.
