I have connected my KC868-COLB to wifi and verified connection to my router, entered Tuya Licence details sent through, generated the QR Code and connected device to Tuya App. It is always showing as offline in Tuya app and I cannot get it connected. I have also tried just with ethernet, and with both ethernet and wifi connected.
What else do i need to do to get my device online in Tuya App?

Yes, I have confirmed there are no spaces before or after any of the fields in the licence information.
I have also confirmed the Central Europe Data centre in my Tuya Developer account
