Hi,
I would need few more information to help you with this problem.
Can you try to resolve your hostname on the simulator's Safari browser?
Also, make sure all of the server information on msso_config.jso (such as port, host name, and prefix, etc.) are correct.
The network reachability error purely means that the host that you are trying to reach cannot be resolved from the device (simulator) that you are trying.
Please let me know.
Thanks,
