Coregistration cannot work

The S-1 Back-geocoding gets stuck and cannot continue processing.


And the corresponding processing file cannot be generated in the file directory.

But not long ago, this function can work normally.
I tried to process on both Windows and Ubuntu, and use both snap7 and snap8, but nothing worked.
I even suspect that it is the network, but I still failed using VPN.
I’m going to crash. How can I solve this problem?

please see the explanation and solution provided here: SRTM ZIP-files are corrupted or not found
