Wow I've never seen that before. Assuming it wasn't a one-off, can you confirm whether there is any network infrastructure messing with access to our servers? Eg can you curl / access https://docker-auth.elastic.co/auth?scope=repository%3Acloud-enterprise%2Felastic-cloud-enterprise%3Apull&service=token-service?

From a bit of googling, it seems like proxies can cause problems here, eg: https://github.com/docker/for-win/issues/894
