I've contacted VMware support, and I am getting no where fast - this is what I originally asked:
Apart from not answering any of the questions, all the support engineer has done so far is point me to these articles, of which none of the stated "resolutions" have worked:
1. Install the appliance using OVFTool 4.4.3
2. Install the appliance using OVFTool 4.3.0
3. restart VMware vService Manager service (vmware-vsm) on the vCenter? and try the installation again.

4. "
Could you please check "vpxd-rhttpproxy-endpoint.conf" you will see vCenter address if it has uppercase characters add a second line right below it as a lowercase
The reason is the Endpoints are case-sensitive and you have added this endpoint:
Then restart the all the services in vCenter.
service-control --stop --all
service-control --start --all
and try to deploy again.
path to the file: /etc/vmware-rhttpproxy/endpoints.conf.d/vpxd-rhttpproxy-endpoint.conf"
5. Replace certificate for vmware-eam https://kb.vmware.com/s/article/2112577
Bit staggered that I can't get a clear answer from Vmware support with regards to my original 4 questions.
