Geoserver WMS only works in JPEG format not PNG

I have around 5,000 Geotiffs that cannot be viewed as image/png in Geoserver 2.17 but work fine if I specify the format parameter as image/jpeg.

For example this URL works:
http://serverName/geoserver/workspaceName/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image/jpeg&TRANSPARENT=true&LAYERS=layerName&exceptions=application%2Fvnd.ogc.se_inimage&WIDTH=464&HEIGHT=768&BBOX=19.6875%2C-41.66015625%2C60.46875%2C25.83984375

But this URL does not:
http://serverName/geoserver/workspaceName/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&LAYERS=layerName&exceptions=application%2Fvnd.ogc.se_inimage&WIDTH=464&HEIGHT=768&BBOX=19.6875%2C-41.66015625%2C60.46875%2C25.83984375

(The only differences in the above URL are the requested format) The failing URL produces the following error in the geoserver.log file:

ERROR [geoserver.ows] -
org.geoserver.platform.ServiceException: Failed to encode the PNG

I have also run a few of the source Geotiffs through gdalinfo and noticed that they have four "bands" listed in the metadata not three. I did not create these Geotiffs so although I know they were created with ESRI software I do not know if the colours are RGB, CMYK or other.

Here is the output from gdalinfo:

In my OpenLayers based application I can ensure the WMS URL specifies the format as JPEG, but end-users using QGIS, Arcmap or ArcPro cannot be expected to know that one of the formats doesn’t work.

Is there any way I can make the image/png format work?

Edit: As per suggestion, tried changing the PNG encoder on the "Image Processing" page from the default "PNGJ based encoder" to "Java own encoder". The java stack trace in the geoserver.log has now changed to:

ERROR [geoserver.ows] -
java.lang.IllegalStateException: No suitable image writer for this output.
