Connection from node-red to openCPN in same PC

Win10 Pro
OpenCPN 5.0.0
node-red 1.0.6


I am using node-red to bring down a lat and long from thingSpeak, putting it through a node-red "function" where it is converted to an NMEA 0183 RMC sentence. I am then trying to input it to openCPN on the same PC via UDP. I have set the port to 192.168.0.105:10110 in node-red and in openCPN. Opening the NMEA Debug Window nothing appears to arrive in openCPN. What am I missing please.

Try setting the port to 127.0.0.1:10110. This is the default localhost address in most systems. (You can also try localhost:10110 but I find more general success with 127).

shouldn't be 0.0.0.0:10110 be the correct syntax for UDP on the local network (including localhost) ?
