Hi,
I'm upgrading the sensor from 5.4.0 to 5.4.0.2.
During the upgrade, the FireSight is unable to manage sensor back. I have checked the sensor version is 5.4.0.1 now.
When I try to add sensor from FireSight, it pop-up a dialogue box "Could not establish a connection with sensor. Make sure the registration keys match, that the software versions are compatible, and that the network is not blocking the connection."
I have double checked the connection and registration keys. FireSight is able to ping the sensor and the registration keys are match.
The FireSight version is 5.4.1.1
I would like to know how FireSight able to manage the sensor and continue the upgrade. Or any way to fallback the sensor version?
Appreciate if anyone can help me to solve this problem. I'm URGENT to fix it. Thanks so much!!
Best regards,
Arthur
