I’m having this recurrent problem with a FIS request in Hungary. I tried not to download some of the data, but it seems there is a lot that is missing or failing because I keep getting this error:
in order to identify the error we need to be able to replicate the request.
Can you send an example of the request that is failing? You can mask the instance iD out, but the rest should be there.
If the problem persists, try splitting your temporal interval. The code you posted works for me if I shorten the time_interval; but I did not try the whole time_interval you define, so the issue might be there.
I’d also suggest you try out the new StatAPI, which supersedes the FIS, and is much more robust with providing better functionality and capabilities. It is already available through sentinelhub-py, see for instance an example in the docs.
