SRTM Autodownload does not finish

Hello !

I have a problem when I want to use a graph which make Calibration (I tried for Oil Spill Detection and Wind Field Estimation). I use the SRTM 3 sec autodownload option for calibration and when I start the processing, it starts to download the SRTM but does not finish and it stay like that :

I use a proxy configuration and I tried with the 5th and 6th versions of the software. So I don’t know what to do, to debug it.

My Best Regards,
