New firmware, now camera wont connect

Was advised of new firmware for one of my cameras (4.9.6.191) so went thru the normal update process. Came back about 10 minutes later to see the camera was off-line with the light on the back of the camera flashing yellow and blue. On my phone I am getting the message “Device is offline, (error code 90)” I have power cycled a few times, no change. Any suggestions?
