This simple change from domain name to domain IP address did the trick! I appreciate you time and effort.
Just to give something back to the community:
Step one :
1) login to MDS using SSH then type: mgmt_cli login user justin_user domain domain_IP_addr > id.txt
2) use this command to extract VPN Star Domains using jq to parse json , extract VPN community and join it with Domain Name, for example.
mgmt_cli -d "domain_IP_address" show vpn-communities-star limit 200 details-level full -s id.txt --format json | $CPDIR/jq/jq -r '.objects[] | select(.type == "vpn-community-star" or .type == "interoperable-device") | [.["name"],.["domain"]["name"]] | join(";")' -r
As I'm no Linux guru, I was not able to extract only VPN Communities with ""use-shared-secret" : false"
