Problem trying to update Espruino Wifi to firmware v106

I am trying to update my Espruino Wifi to v106. It was recently updated to v105 without any issues.

Here's what i've tried:

1. Put the Espruino Wifi into boot loader mode, the red and green light pulsate in sequence.
   
2. Click the flash firmware button.
   
   

Error popup in the web ide says -

Firmware for this device can't be updated from  the IDE at the moment. 

(I used the above steps to update to v105 last week and it was successful)

1. Put the Espruino Wifi into boot loader mode, the red and green light pulsate in sequence.
   
2. Click flash from file button and locate previously downloaded - espruino_2v06_wifi.bin
   
   

This time I see:

Connected to COM1 (No response from board)
Initializing...
Error Flashing: Can't find STM32 bootloader. Make sure the chip is reset into bootloader mode by holding down BTN1 while pressing RST
Disconnected from COM1
