Pulse App


I'm unable to login through pulse app from one of my android devices. It shows network problem every time I try to log in where as it's no the case in other similar device. I have reinstalled the app multiple times and checked the network as well changed the password. It was working well in that device until this morning when I changed my password as my previous password expired. Can you help me with it? My device is Galaxy J2.


Thank You.
