LTA downloaded Sentinel 1 imagery corrupted


I have downloaded quite a few Sentinel-1 IW GRD images from the archive via the python API and almost every zipped folder is corrupted.

Example image: S1A_IW_GRDH_1SDV_20190412T221928_20190412T221953_026763_030196_962B

When trying to run the imagery with snappy I get the error when I try to open them:

SEVERE: org.esa.snap.core.dataio.ProductIO: Error attempting to read: Z:\free_sat_downloads\sentinel1\nb2019\GRD\florenceville_copy\ with plugin reader org.esa.s2tbx.dataio.s2.ortho.plugins.Sentinel2L1CProduct_Multi_UTM13S_ReaderPlugIn@3bd6ba24

and this error when I try to unzip the folder with 7zip (“unexpected end of data” error):

I have contacted support but I don’t know if they can help much and I read through this thread but it seems like there was no resolution.

I have also tried changing the “.zip” manually to “.nc” after reading this. I can then read in the file with snappy but as soon as I try to use it I get, for example:

s1_read = snappy.ProductIO.readProduct(r"Z:\free_sat_downloads\sentinel1\nb2019\GRD\florenceville_copy\")
Traceback (most recent call last):
  File "<input>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute 'getSceneRasterHeight'

Any idea what to do next?
