{: #troubleshoot-delete-subnet} {: troubleshoot} {: support}

You attempted to delete your subnet, and received an error. {: shortdesc}

The following error message appeared when you attempted to delete a subnet: {: tsSymptoms}

{: caption="Delete subnet error" caption-side="bottom}

When you create a pool and associate a health check to that pool, {{site.data.keyword.dns_short}} automatically provisions an appliance that attaches to a network interface in your subnet. {: tsCauses}

To remove the subnet, first remove the health check configuration associated with your pool and then try deleting your subnet again. {: tsResolve}

To remove the health check, take the following steps:

1. Navigate to Global load balancer > Origin pools
2. Click the overflow menu and select Edit
3. In the side panel that appears, scroll to the Health monitoring section and select No health check from the drop down menu
4. Click Save

You do not need to delete the pool itself. {: note}
