Hey, hope you are doing fine
in my experience this is a certificate error, VMware products will always fail if certificates aren't replaced correcly.
Can you please attach the following logs vpxd.log, (located on /var/log/vmware/)
In addition to that, are you running an embedded PSC or an external PSC?
Have you tried this:
Regenerate a New VMCA Root Certificate and Replace All Certificates
Regenerate Self-Signed Certificate in vSphere 6.5 - VMWare Insight --> Try this first
Hope this works
