SSLError when using cdsapi

Software and Tools API
1

Dear ECMWF team,

When I use the cdsapi package to download ERA5 data, I can successfully submit my request; however, once the request is ready, the code keeps failing to actually download the file and throws the following error:

Error downloading data for 2003-04-15: HTTPSConnectionPool(host=‘cds.climate.copernicus.eu’, port=443): Max retries exceeded with url: … (Caused by SSLError(SSLZeroReturnError(6, ‘TLS/SSL connection has been closed (EOF) (_ssl.c:1147)’)))
Yet the same file can be downloaded without any problem by clicking the “Download” button in the CDS web interface. What could be causing this discrepancy?

Thank you very much in advance for your clarification and support!
Best,

Meixian Ji

Try to initialize the client as follows:
cdsapi.Client(verify=False,)
