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:
[[["Easy to understand","easyToUnderstand","thumb-up"],["Solved my problem","solvedMyProblem","thumb-up"],["Other","otherUp","thumb-up"]],[["Hard to understand","hardToUnderstand","thumb-down"],["Incorrect information or sample code","incorrectInformationOrSampleCode","thumb-down"],["Missing the information/samples I need","missingTheInformationSamplesINeed","thumb-down"],["Other","otherDown","thumb-down"]],["Last updated 2025-09-04 UTC."],[],[],null,["# Troubleshoot issues\n\nThis page explains various error scenarios, and provides guidance for resolving\nthe errors.\n\nConnectivity error scenarios\n----------------------------\n\nThis section explains connectivity issues your instance can encounter.\n\n### Connection error caused by firewall rules\n\nFirewall rules might cause connection errors by blocking the ports that\nMemorystore for Redis Cluster uses.
