On November 23rd 2015, the out-of-the-box default certificates provided with Command Central 9.6, 9.7, 9.8 and 9.9 for securing SSL communication expired. While we recommend customers to replace these certificates with their own custom certificates, we realize that some customers are using these out-of-the-box certificates.
If you are still using these certificates and you have configured Command Central to use HTTPS, then Command Central will no longer be able to connect to any managed installations.
