Hello SNAP community
I am working with SNAP on a high-performance cluster.
The terrain correction using SRTM dem is unable to download the DEM zip file. It tries to download the file recursively and gets stuck. Even after manually downloading the zip file and placing it in the auxiliary files folder, SNAP fails to use that (error in opening zip file) and tries to redownload the file.
This problem only arises in high-performance clusters with proxy and not on a local machine
This problem has been reported multiple times and I think there has been no patch for this.
.
The only solution I could find was that dem is not configured to be downloaded over proxy as said by @johntruckenbrodt here
