ASA fails to reconnect to Security Cloud Control after reboot

An ASA reconnection failure is a connectivity issue that

  • occurs when an ASA device fails to reconnect to Security Cloud Control after a reboot

  • happens because the ASA has fallen back to using an OpenSSL cipher suite that is not supported by Security Cloud Control's Secure Device Connector (SDC), and

  • requires troubleshooting to test for the cipher suite issue and apply remediation steps.

Symptoms

  • ASA reboots and Security Cloud Control and the ASA fail to reconnect. Security Cloud Control displays the message, "Failed to reconnect."

  • When attempting to onboard an ASA, Security Cloud Control displays the message: Certificate could not be retrieved for <ASA_IP_Address>.
