[MiILLION]

I got this error when I running the codes
Connection error: [HTTPSConnectionPool(host='cds.climate.copernicus.eu', port=443): Max retries exceeded with url: /api/v2/tasks/39888b13-7056-4d1f-9999-90770e7fe8d9 (Caused by ProxyError('Unable to connect to proxy', OSError(0, 'Error')))]. Attempt 7 of 500.

I tried to add a timeout,but it was of no use.
