From the NSX Manager logs:

I found this snippet – which showed the nsx-user had User account expired

2019-03-06 10:25:31.302 GMT ERROR http-nio- SoapBindingImpl:133 - SOAP fault
javax.xml.ws.soap.SOAPFaultException: Password of the user logging on is expired. :: Password of the user logging on is expired. :: User account expired: {Name: nsx-user, Domain: vsphere.local}



Reset the password for the nsx-user in vCenter. Both lookup service and vcenter connections were instantly restored.
