An engineer is troubleshooting a vEdge router and identifies a "DCONFAIL ?DTLS connection failure" message. What is the problem?

Memory issues usually manifest as performance problems or system instability, not specifically as a DTLS connection failure message.

A certificate mismatch would typically generate a more specific error message related to certificate validation or authentication failure.

An organization mismatch prevents the vEdge from joining the fabric, leading to specific 'organization name mismatch' errors rather than a generic DTLS connection failure.

DTLS connection failures typically point to underlying network reachability issues, such as routing problems, firewall blocks, or NAT issues, preventing the vEdge from establishing a secure control plane connection to vSmart or vBond.
