HNS_NETWORK_NOT_FOUND

HNS_NETWORK_NOT_FOUND is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the referenced HNS network no longer exists or was not available under the supplied identifier.

What to check

  • List the current HNS or container networks and verify the exact name or GUID used by the caller.
  • Check whether a cleanup, Docker reset, or host restart removed the network before the operation ran.
  • Create or discover the required network before attaching endpoints or applying policies to it.
