Unity Catalog storage credential fails although same Access Connector works in another credential

In Azure Databricks Unity Catalog, I have two storage credentials that use the same connector_id / Azure Databricks Access Connector.

One credential works and can access ADLS Gen2 successfully, but the other fails with:

Failed to access cloud storage: [AbfsRestOperationException] () exceptionTraceId=de567037-b3b2-414c-8908-b3174c490b22

Both credentials appear to reference the same Access Connector. I have checked that the working credential can read/list/write the ADLS Gen2 path.

What could cause one Unity Catalog storage credential to work while another credential using the same Access Connector fails?
