new Tuya Plug - not flashing

I have a new Tuya plug which is not being flashed.
It has ESP eprom on it I believe because the device name starts with ESP

When I use the tuya-convert tool, it connects to the AP and receives IP address 10.42.42.22 (not 10.42.42.42)

and the smartconfig fails.

I get this log on psk screen:

```

is this a new device ?
what can I do to flash it with Tasmota firmware ?

If I can contribute by supplying information from current firmware I would happily do that.
if that's not required, I will flash using USB flasher. But I don't know how to connect this to my ESP flasher.
where can I find info on it ?

Start by reproducing the failure with the tuya-convert tool and review the smartconfig and psk screen logs, including the device IP, ID, PSK, and SSL errors. Compare the behavior with the documented Tuya and ESP flashing process; done means establishing whether this device is supported and documenting a working tuya-convert or USB flasher path.
