Symptoms

The CloudLink SSL Web certificate is expiring.By default, CloudLink Center uses a self-signed certificate. When connecting to CloudLink Center, the web browser may display several security warnings. These warnings are displayed because self-signed certificates do not have the same level of trust as certificates issued and signed by a trusted certification authority (CA). 

Cause

The SSL certificate date was set to expire.To stop these warnings from being displayed, obtain and upload to CloudLink Center a certificate that has been signed for CloudLink by a trusted CA.You can upload an externally generated certificate and private key, or generate a certificate signing request for a private key generated by CloudLink Center.CloudLink supports two formats for externally generated keys and certificates: Privacy-Enhanced Electronic Mail format and PKCS #12 format.

Resolution

To resolve this issue, upload a new SSL certificate to the CloudLink appliance. Note: When uploading a new certificate and an optional private key, the web server restarts and the connection is terminated. After uploading a certificate signed for CloudLink Center, verify the subject, fingerprint, and end date to ensure that it is the certificate that is wanted. Steps: Log in to CloudLink Center.Click Server > SSL > Upload. The Upload Web SSL Certificate is displayed.In the Upload Web SSL Certificate dialog box, enter the following information: From the Certificate Format list, select the required certificate format.In the Certificate box, click to select the certificate.In the Key box, click to select the key. Click Upload. See page 123 of the Admin guide for more information: https://dl.dell.com/content/manual25809037-dell-cloudlink-administration-guide.pdf
