The missing images are missing from developmentseed API index, which is used by TSD as the default catalogue as it doesn't require authentication.

If you use the scihub API by adding the optional parameter --api scihub to your cmdline you'll get more images. This requires authentication with your Copernicus/Scihub credentials stored in the COPERNICUS_LOGIN and COPERNICUS_PASSWORD environment variables.

python3 get_sentinel2.py --geom output/sabine_pass.geojson -b B04 -s 2017-5-3 -o output --api scihub

The EO browser images that are still missing from this TSD call should be only incomplete images (ie images that don't cover the entire geojson polygon) as TSD searches only for images that contain the polygon while EO browser searches for images that intersect the polygon.
