Answer 1

unfortunately this error is not due to sentinelsat api.

As error says, you are

Trying to download an offline product.

You can download sentinel products that are online and not offline.

Sentinel products that are online are those of last 1 year, you are trying to download older products.

If you want an older product go to sentinel scihub find a product, request it and it will be online later (could need 1 day or more, or if you are lucky a few hours later).
