# Pairing Failure - Retrieving Cluster Information If your Platform9 vCenter gateway virtual appliance reports a failure to pair due to an error while retrieving cluster or datastore information, this means that one of your hosts or datastores was not accessible, or could not be queried for its usage statistics. Please ensure that your vCenter hosts and datastores are connected and accessible, and reporting usage data to vCenter. Once this is done, the pairing status should automatically update to allow you to proceed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.platform9.com/managed-openstack/5.8/troubleshooting/vmware/troubleshooting-issues-vmware-gateway-auth.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
