Dear Tomas, note that these are 4 Float32 bands. When you open it on QGIS, it automatically applies some contrast-stretch and band selection, making them looks-like an RGB dataset. On GeoServer, you can use the 3 bands channelselection+contrastEnhancement SLD you have applied. I think there is some issue when applying the bandSelect (as reported on your logs) to go from 4 bands to 3 bands in order to write it as JPEG (which only supports 1 or 3 bands). Could you please check if there is already a JIRA on GeoServer reporting the same issue and, if not, create a bug-report with sample data and SLD to replicate the problem?
