I am a Copernicus Data Space Ecosystem user and am trying to download Sentinel-2 L1C data for a specific region in France (200 km²) between 2015 and 2024. I am using the Sentinel Hub Python library to achieve this.
The code works fine when I request data visualization without saving it (using request_all_bands.get_data()). However, when I try to download the data in TIFF format using request_all_bands.get_data(save_data=True) or request_all_bands.save_data(), I encounter an error:
DownloadFailedException: Failed to download from:
https://services.sentinel-hub.com/api/v1/process
with HTTPError:
401 Client Error: Unauthorized for url: https://services.sentinel-hub.com/api/v1/process
Server response: "{"status": 401, "reason": "Unauthorized", "message": "You are not authorized! Please provide a valid access token within the header [Authorization: Bearer <accessToken>] of your request.", "code": "COMMON_UNAUTHORIZED"}"
Questions:
- Is downloading data for personal, non-commercial use restricted for Copernicus Data Space Ecosystem users?
- If downloading data is allowed, what steps do I need to take to successfully download Sentinel-2 L1C data in TIFF format for my analysis?

Additional Information:
I have confirmed my client ID and secret are set correctly in the SHConfig object.
I have verified that my Copernicus Data Space Ecosystem account is active.
I would appreciate any insights or solutions to help me download Sentinel-2 L1C data using my free Copernicus Data Space Ecosystem account.
Thank you for your support!
