Technical Tip: FortiSOAR SME Connection Failure

The issue occurs when the SME server certificate Common Name (CN) or Subject Alternative Name (SAN) does not match the Address in the FortiSOAR configuration.

In the Configuration Status column, Not Configured means that FortiSOAR cannot establish a successful SSL handshake with the SME using the provided certificate and credentials.

To resolve the FortiSOAR SME connection failure, follow these steps:

1. Ensure the FortiSOAR node and SME server are on the same subnet and there is no firewall blocking the connection.
2. Check the FQDN with ping to ensure it can be pinged.
3. Regenerate the SME's RabbitMQ SSL certificate using the correct FQDN. The CN or SAN in the SME's server certificate must match the FQDN configured in FortiSOAR.
4. Replace the certificates and restart the SME service:

systemctl restart rabbitmq-server

By following these steps, the SME should register successfully with FortiSOAR.
