Connectivity error scenarios

This section explains connectivity issues your instance can encounter.

Connection error caused by firewall rules

Firewall rules might cause connection errors by blocking the ports that Memorystore for Redis Cluster uses. For both of your instance's Private Service Connect endpoints, allowlist ports 11000 through 13047. For more information about these endpoints, see Reserved network addresses.

Connection error caused by organization policies.

You can have an organization policy that blocks your Private Service Connect connections to your Memorystore for Redis Cluster instance.

If your organization policy uses the .restrictPrivateServiceConnectProducer policy, then allow list the 961333125034 folder number, which is a folder specifically for Memorystore for Redis Cluster. For example:

name: organizations/Consumer-org-1/policies/compute.restrictPrivateServiceConnectProducer
spec:
    rules:
      - values:
          allowedValues:
          - under:folders/961333125034

If your organization policy uses the .disablePrivateServiceConnectCreationForConsumers policy, you should allow list SERVICE_PRODUCERS. For example:

name: organizations/Consumer-org-1/policies/compute.disablePrivateServiceConnectCreationForConsumers
spec:
    rules:
      - values:
          allowedValues:
          - SERVICE_PRODUCERS
