Installed a new MID Server to do a Network Discovery. Received the following error after setup was completed.

AMBClient exception when instantiating a AMBClient. Connection is not successful

What would cause this issue and more importantly what is the best direction to resolve getting this error message.

FYI: Discovery was successful for SNMP Behavior of the network device.

Update: IS there a way to find the port used fo the

Asynchronous Message Bus communication.

Trying to determine if this is a port being blocked on the firewall, Port 443 is open for Mid Server to use for communication to the instance. Is the AMB using this port as well.

Checked with FW team and they do not see any denies from MID Server to SN Instance

HI,

What about the memory requirements. I saw this recently when the memory of server was low.


Thanks,
