Not able to use ota, update always fails, is the verison to old?

[TKaluza]

Hello!
I tried differenty ways to flash a Shelly RGBW2 ota. I also hosted a small server for downloading the file via my network without https and a static ip but I always get:
"http://192.168.178.24/ota?url=http://192.168.178.100:8080/mg2tasmota-ShellyRGBW2.zip"
{"status":"updating","has_update":false,"new_version":"20221027-100516/v1.12.1-ga9117d3","old_version":"20221027-100516/v1.12.1-ga9117d3"}

and it seems to me it will not use the provided "older" firmware. But I do not know.
Any suggestions what I'm doing wrong?

Same here for the Shelly Duo RGBW through the original link.

@TKaluza I just tried this on a RGBW2 and found that it was rejecting the firmware because the name didn't match. It was trying to write rgbw2 firmware when it needed to be called rgbw2-color.
This RGBW2 isn't new, perhaps in a recent shelly firmware they changed this?

I recompiled the RGBW2 firmware with that name changed and it flashed successfully for me:
