3792165 - Error "Connection refused: localhost:10001" loop after upgrade to SAP Commerce 2211-JDK21.14+ in local environment

Symptom

After upgrading SAP Commerce Cloud to 2211-JDK21.14 or later, the local server log repeatedly shows a Connection refused: localhost:10001 error every second, even though toggle.combined.eventing.enabled=false is set.

The exact wording of the stack trace can vary slightly between environments (thread name, IPv4 vs IPv6 loopback, and the outermost exception type), but the key signature is always the same: the webhookservices queue polling path fails to connect to localhost:10001.

Both of the following variants describe the same issue:

Variant A

ERROR [task-scheduler-x] [ErrorHandler]  unexpected exception caught
org.springframework.messaging.MessagingException
    at org.springframework.integration.endpoint.AbstractPollingEndpoint.pollForMessage(...)
    ...
Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException:
    finishConnect(..) failed with error(-111): Connection refused: localhost/127.0.0.1:10001


Variant B

ERROR [<polling-thread>] [ErrorHandler] unexpected exception caught
    at de.hybris.platform.core.TenantAwareThreadFactory$1.internalRun(TenantAwareThreadFactory.java:163)
Caused by: reactor.core.Exceptions$ReactiveException:
    io.netty.channel.AbstractChannel$AnnotatedConnectException:
    Connection refused: localhost/[0:0:0:0:0:0:0:1]:10001
    at com.azure.spring.integration.storage.queue.inbound.StorageQueueMessageSource.doReceive(StorageQueueMessageSource.java:54)
    at de.hybris.platform.webhookservices.alod.TenantAwareMessageSource.receive(TenantAwareMessageSource.java:76)

In both cases the stack trace goes through the same path:
TenantAwareMessageSource.receive → StorageQueueMessageSource.doReceive → netty finishConnect (failed) → Connection refused: localhost:10001. The error repeats every second and does not stop.
