Missing HLS data

[morenoj11 (Jose Moreno Ortega)]

I have noticed that there are some cases in which I get missing data in the requested image, even when having a broad time observation. For example, the image below:

Is this behavior expected? Am I missing something here?

Below my request,
thanks in advance!

Hi @morenoj11 ,

It seems that your area of interest is in the UTM 38N zone. If you set the CRS to EPSG:32638 in your request shown as following, the issue should be fixed.
