Having trouble connecting ESP node to Domoticz controller

[orbitcoms]

I have a DS1820 temperature node on 192.168.1.15. The Domoticz is hosted on Raspberry pi 3 (port 8081). The pi has 2 Wifi adapters (Wlan0 on 192.168.1.161, wlan1 on 192.168.1.162).

Wlan0 is the pi built-in wifi
Wlan 1 is a USB wifi dongle
AP is an ESP8266 set up as softAP - ssid = "TemperatureNetwork"

If I navigate to either of the pi wifi URL, I get the Domoticz screen and all is ok.

I can access the node OK (192.168.1.15)

I have set up the node to connect to wifi on Wlan1 (ssid = "TemperatureNetwork" and set the psk accordingly.

In the controller page I have set up Domoticz HTTP, IP address 192.168.1.162, port 8081 and ticked to enable then saved.

Then I set up the DS1820 and it is working fine. But, the node does not seem to connect to the Domoticz controller and I am not sure what steps to take next to resolve this.

Here is a dump of the ESP node coms output. You can see that is gets the temp ok but fails to deliver.
