You have broken connection to ‘local’ SPM because of expired SSL certificate
As described in the article to address this problem you needed to switch all SPM connections to use HTTP, including ‘local’ SPM node.
Use HTTP communication. To switch to HTTP, in the Command Central web user interface, clear the “Use SSL” checkbox, specify the Platform Manager HTTP port and refresh the page.
Once you switch local node to HTTP your platform list would come up as non empty.
The above page also provides this update:
Dec 16 UPDATE: The 9.9 fix (CCE 9.9 Fix2) is available on SDC as part of the updated Command Central Bootstrap Installer which can be downloaded from https://empower.softwareag.com/Products/DownloadProducts/sdc/default.asp and re-executed against existing CCE 9.9 GA and/or CCE 9.9 Fix1 installation created either using CC Bootstrap Installer (cc-all-9.9-fix1-) or the regular SAG Installer. You can also use updated cc-all-9.9-fix2- CC Bootstrap Installer to setup new installations of CCE 9.9.
