SX20 - Registration via MRA issue - GET Edge Config:Peer certificate cannot be authenticated

Hi

We have CUCM 11.5 and exp-c&E 8.9 on production. We have installed Digicert pulic CA certificate on Expressway.

We have also registered Cisco 8800 IP phone via MRA. (Through internet)

But when we try to register SX20 through MRA (Internet), we are getting error message of certificate.

Digicert certificate is already installed on Expressway and also listed under SX 20 trusted CA.

Because Digicert is installed we are able to register 8800 IP Phone.

Pls. suggest why we are not able to register SX20.

Error on SX20 is : GET Edge Config:Peer certificate cannot be authenticated with given CA certificate.

SX20 is running TC7.3.8.6a15db5

Also I have attached the screenshot of error.
