BYOC Edge Registration 401 Unauthorized after Key Rotation

We are deploying a premium app integration via AppFoundry that relies on direct platform API calls from a BYOC Edge cluster. After rotating the private key used for JWT generation, the edge nodes fail to register. The /api/v2/edge/registrations endpoint returns a 401. The JWT is signed correctly using the new private key, and the corresponding public key is uploaded to the organization settings in the portal.

“Ensure the public key uploaded matches the private key used for signing. Key pairs must be generated within the last 24 hours to comply with rotation policies.”

The documentation mentions the 24-hour window, but this key was generated five minutes ago. We are using the genesys-cloud-nodejs SDK v3.5.0 for the JWT creation logic. The iss claim matches the integration ID, and the aud claim points to the correct org UUID. The edge cluster is in us-east-1.

Has anyone seen a lag in the propagation of the new public key to the edge registration service? We have waited over an hour with no success. The old key still works if we revert the integration settings, confirming the issue is strictly with the new key pair validation on the server side.

The official documentation states that BYOC Edge registration relies on the genesyscloud_byoc_edge resource for key management in Terraform. Rotating the private key locally does not automatically update the public key stored in the Genesys Cloud tenant unless the provider is explicitly notified. The 401 error occurs because the edge cluster is signing JWTs with a private key that the platform does not yet recognize as valid for that specific edge ID. Check the genesyscloud_byoc_edge resource configuration to ensure the public_key attribute is updated with the new corresponding public key. If using CLI or API, the /api/v2/edge/edges/{edgeId} endpoint must be patched with the new public key content.

resource "genesyscloud_byoc_edge" "my_edge" {
 name = "BYOC-Edge-Primary"
 description = "Primary BYOC Edge for AppFoundry"
 
 # Ensure this matches the new public key after rotation
 public_key = file("${path.module}/keys/new_public.pem")
 
 # Optional: Force replacement if key change is not detected automatically
 lifecycle {
 ignore_changes = [tags]
 }
}

Verify the key format is PEM-encoded and does not contain extra whitespace. After updating the resource, run terraform apply to push the new public key to the tenant. The edge nodes will then validate against the correct key pair. Monitor the edge registration logs for a 200 OK response. If the issue persists, check the client secret rotation script for scope mismatches, as seen in previous OAuth issues. The edge registration process is strict about key validity and expiration times.

The problem here is the platform hasn’t synced the new public key.

resource "genesyscloud_byoc_edge" "my_edge" {
 public_key = file("new_public.pem")
}

Run terraform apply to push the update. The 401 clears once the tenant recognizes the new key.

The best way to fix this is…

Cause: The tenant still holds the old Zendesk-style static key, not the new GC dynamic one.

Solution: Push the updated public key via Terraform.

resource "genesyscloud_byoc_edge" "my_edge" {
 public_key = file("new_public.pem")
}

Run terraform apply. The edge syncs immediately. Much cleaner than manual Zendesk config updates!
