tuya-convert: Can't connect to device

I have Gosund WP3 devices I’m trying to convert to Tasmota. Running tuya-convert on a RPI zero with Wifi Dongle, and serial console. I got my phone to connect to vtrust-flash at 10.42.42.26. Blue light on device is blinking. Here what I get when trying start_flash:

hvxl@rpia:~/tuya-convert$ ./start_flash.sh

IMPORTANT
1. Connect any other device (a smartphone or something) to the WIFI vtrust-flash
   This step is IMPORTANT otherwise the smartconfig may not work!
2. Put your IoT device in autoconfig/smartconfig/pairing mode (LED will blink fast). This is usually done by pressing and holding the primary button of the device
   Make sure nothing else is plugged into your IoT device while attempting to flash.
3. Press ENTER to continue

I’m a Linux NOOB, so don’t know what to make of any of the log info, although it look like a connection couldn’t be made.
