Hi Andreas

Could it be that your whole publish folder gets indented in a "linux-x64" folder, which is not recognized by the DXP platform? In that case, you could try moving the whole output one level out before deploying.

Hi Stefan.

No there is no linux-x64 folder in my package. I outputted the content of the folder before i packaged it and this is what it looks like (with exception that I've shrunk it abit to viewing perposes and that I don't want to write everything in this folder for security purposes)

Hi Andreas, I'm pretty sure you shouldn't have top most wwwroot folder - so you need to put contents of that folder in the package.
