STATUS_ADDRESS_ALREADY_EXISTS

The local transport address is already in use

Find the endpoint that already owns the requested local address or binding tuple. Reusing the same address requires the API-specific sharing semantics; otherwise select a different binding or release the previous owner.

This status is raised when opening or associating a transport address that is already present. It is a local binding conflict, not proof that a remote host is misbehaving.

What to inspect

  • Check local address, port, protocol, and compartment.
  • Find the process or driver that already owns the endpoint.
  • Review exclusive-address and reuse-address policy.
