Changing custom domain doesn't kill connections


I’m changing my custom domain from .
I have k8s resources alive requesting M2M tokens from .
When i delete the custom domain from auth0 (, attach another (, attach the old domain ( to other cloud resource i have - the requests are still going to auth0 but i get error. this is because the connection is still alive and not disconnected by the tenant.
