[ATP/FLEX] Why the firewall cannot access the Nebula in Monitor Mode again?

Scenario :

The user may encounter a situation where, after removing the device (in Monitor Mode) from the org and adding it to the license & inventory again, the device still cannot be online in Monitor Mode on Nebula. What is the possible reason, and how can this be resolved?"

Answer :

The possible reason is that the user forgot to assign the device to the corresponding site and allow it to access Nebula again. For instance, if the user has an ATP500 but forgot to assign it to the previous site 'Site A,' the solution is to assign 'Site A' to the ATP500 again, as shown below:

Once it's done, wait a moment, and the ATP500 will be online again.
