I'd first check the firewall to ensure that there are no rules blocking "Cloud communication" for the cameras. (Help>Firewall info within dashboard)
If this is fine, I'd then check the switches/devices in the path to ensure that there are no ACL's which could be blocking the communication.
If this is fine, take packet captures from the switch-port where the cameras are connected to see what's going on. If traffic is passing, I'd take a similar capture from the WAN interface of the Firewall to ensure it's transversing your LAN fine.
