Cause

TLS 1.0 and 1.1 protocols are being restricted on the OS, but the EEM server is still able to use those protocol versions.  

Resolution

- Reconfigure EEM + CA Directory to use TLS 1.2 only  (https://knowledge.broadcom.com/external/article?articleId=74517)

- Stop igateway, dxserver,  start dxserver, igateway and then restart WCC
