CNE controller fails to use the new certificates after the root CA is updated.
GRPC communication fails, TMM is not configured.
After the Root CA update and reissued certs, TMM’s certificate chain uses a different root CA than the controller’s.
Restart the controller.
Improve TLS error handling, to refresh certs in cases where Root CA mismatch is the reason for failed communication.
