Environment

VMware NSX-T Data Center 3.x
VMware NSX-T Data Center
VMware NSX 4.0.0.1

Cause

NSX environments that started on older versions of NSX, typically pre-3.x may still have old certificates in the system.
NSX 3.2.x and 4.x fails to handle certificates with an old service type as they are not used on these versions.

Resolution

This is a known issue, currently there is no resolution.

Workaround:
Identify if the system has any certificates using old service types by running the API to list certs

GET /api/v1/trust-management/certificates 

Check for the "service_types" field.

Certificates with any of the following service_types will cause this issue
 

"Node API Certificate"
"MGMT_PLANE_DNE"
"Client Authentication"
"Cluster API Certificate" 

If the certificate is in use, make note of the node UUID in the "used_by" field.

The certificate will first need to be released from the node and then deleted

ssh to any NSX Manager as root user and for each cert 

curl -k -X POST -H "Content-Type: application/json" -H 'X-NSX-Username:admin' -H 'X-NSX-Groups:superuser' -d '{"node_id":"<NODE_UUID>"}'  "http://127.0.0.1:7440/nsxapi/api/v1/trust-management/certificates/<CERT_UUID>?action=release"
curl -k -X DELETE -H "Content-Type: application/json" -H 'X-NSX-Username:admin' -H 'X-NSX-Groups:superuser'  "http://127.0.0.1:7440/nsxapi/api/v1/trust-management/certificates/CERT_UUID"

Note if the certificates are used by a Principle Identity solution such as Tanzu, it may be necessary to delete the associated cluster deployment and redeploy it to free up the problem certificate.
