Linkerd-viz: FailedDiscoveryCheck

We’re running Linkerd Viz 2024.8.3, and the “v1alpha1.tap.linkerd.io” ApiService is continuously spitting out the following errors:

“FailedDiscoveryCheck: failing or missing response from https://10.x.x.x:8089/apis/tap.linkerd.io/v1alpha1: Get “https://10.x.x.x:8089/apis/tap.linkerd.io/v1alpha1”: remote error: tls: unknown certificate authority”

Does anyone know why this could be happening, and how we might be able to fix this?
