• When navigating to the Network Operations tab in the VCF Operations UI, the following error is displayed:
  
  

  Error: "Encountered an error. Verify system and operations-network appliance health" under Network Operations in VCF Operations 

• Looking at the Network Operations logs we saw the below error:

  Log location: /var/log/arkin/restapilayer/restapilayer.STDOUT-2026-03-24-10.44.12.log
  
  

  Caused by: com.nimbusds.jose.jwk.source.JWKSetRetrievalException: Couldn't retrieve JWK set from URL: No subject alternative DNS name matching example.com found.         at com.nimbusds.jose.jwk.source.URLBasedJWKSetSource.getJWKSet(URLBasedJWKSetSource.java:71) _[nimbus-jose-jwt-9.41.1.jar:9.41.1]

Environment

VCF Operations 9.0.x 

VCF Operations for Networks 9.0.x 

Cause

The integration fails because the SSL certificate assigned to the VCF Operations cluster is missing required Subject Alternative Names (SAN). Specifically, the certificate SAN must include the shortname, FQDN, and IP address for all nodes within the VCF Operations cluster.

Resolution

To resolve this issue, renew the VCF Operations certificate to ensure it contains the correct SAN attributes for all cluster members.

• Generate a new Certificate Signing Request (CSR) or certificate that includes the Shortname, FQDN, and IP address of every node in the VCF Operations cluster.
• Apply the renewed certificate to the Aria Operations cluster.
• For detailed procedural steps on certificate configuration, refer to the official documentation: Configure a Certificate For Use With VMware Aria Operations.
• Once the certificate is updated, retry the integration in the Network Operations tab.
