The bulb sends no Host header, no User-Agent and the request is malformed, so it can’t download any firmware from anywhere.
And the bulb returns:
{
"seq": 2,
"error": 408
}
Now my bulb is stuck at "fwVersion": "1.4.1", I don't know how to exit DIY mode and check for an updated firmware that might fix this issue and I also cannot flash Tasmota because of the above error.
I bought this bulb, updated to latest firmware then turned on DIY mode.
Then I wanted to flash tasmota-latest-lite.bin from here: http://sonoff-ota.aelius.com/
But it did not work, so i moved the file to my lan on an nginx server, and you can see below the errors i get.
