Now I need to fix this problem. The error code is 1501, and I do not know why I have this problem. Pulse was working correctly two days ago. What could be happening? Help me please. Thanks!
https://www.pulsesecure.net/download/techpubs/current/1057/pulse-client/pulse-secure-client-desktop/5.3rx/ps-pulse-5.3r3-error-msgs.pdf says the error code is:
" 1501 kMsg8021xAMErrNoWindowsProfile No SSID(s) in range for connection request. Verify your wireless network configuration and SSID signal strength and then try the operation again."
So the wireless adaptor cannot connect to the wireless access point. Do you have a working wireless connection?
Hopefully you have found a way to rectify this, if you have, can you please share? Along the same lines as @mspiers mentioned, did you adjust the 802.1x profile on the Pulse installation around the time you saw the failure?
