WARN AD No reachable DNS server configured; TMC tmc.tippingpoint.com TCP connection failed; Version output
This error message is generated when the device is unable to communicate with the Threat Management Center (TMC). Most likely the DNS configuration is incorrect and the device is unable to resolve the path to the TMC. Check the device configuration for correctness.
Note: The TMC no longer responds to ICMP request (PING) so you will not be able to use this tool to verify the path.
