geoserver returns black image on aerials - image

Question

I am trying to upload aerial photos to geoserver to be shown as background. But everytime the image is black instead of detailed satellite image. Also tried on single tif files, but same result. Anybody have experience with this issue and know a solution?
I use ImageMosaic as plugin to upload the tifs.
This is the result of gdalinfo:

Answer 1

We recently found out the compression type was wrong. WEBP instead of Geotiff. It will be resolved.
