I have a problem when trying to add an advertised address in Kamailio 5.4.2

we have a checf config that is populating various variable. some of these are for the Listeners

we have this working and Im getting all protocols for the listeners based on the non _TLS Vars but the TLS config is trying to resolve ADVERTISE_NAT_ADDRESS_TLS. If I try and quote the variable "ADVERTISE_NAT_ADDRESS_TLS" id get an error saying 1.2.3.4:5061 is not resolvable

therefroe I have udp,tcp and tls listeners all on the default ports where i need the tls on port 5061 ans not 5060

listen LISTEN_EXTERNAL_SOCKET advertise ADVERTISE_NAT_ADDRESS name = "ext"

listen LISTEN_INTERNAL_SOCKET  name = "int"

listen LISTEN_EXTERNAL_SOCKET_TLS advertise  name = "ext-tls"

listen LISTEN_INTERNAL_SOCKET_TLS  name = "int-tls"

the Vars are defined as

#!define TOPO_NAT

#!substdef "!LISTEN_EXTERNAL_SOCKET!10.10.10.10:5060!g"

#!substdef "!LISTEN_INTERNAL_SOCKET!10.10.10.10:5080!g"

#!substdef "!ADVERTISE_NAT_ADDRESS!1.2.3.4:5060!g"

#!define ENABLE_TLS

#!define TLS_CONFIG_FILE "chef-managed/tls.cfg"

#!substdef "!LISTEN_EXTERNAL_SOCKET_TLS!tls:10.225.73.16:5061!g"

#!substdef "!LISTEN_INTERNAL_SOCKET_TLS!tls:10.225.73.16:5061!g"

#!substdef "!ADVERTISE_NAT_ADDRESS_TLS!1.2.3.4:5061!g"
