If you are still experiencing issues it's time to look at the error messages.

...



What type of error are you seeing?

'Timed out'

...

If you're seeing an error message which mentions 'timed out' like the example below:

Diagnosis: This is likely due to network issues causing delays in the communication between the your system and the CDS.

...

Solution: The best way round this is to add the "timeout=600" (or longer) option for the timeout duration in seconds, to your CDS API request :

c =cdsapi.Client(timeout=600,quiet=False,debug=True)


‘Proxy’

If the message mentions ‘Cannot connect to proxy’ 

WARNING Recovering from connection error [HTTPSConnectionPool(host='cds.climate.copernicus.eu', port=443): Max retries exceeded with url: /api/v2/resources/cems-fire-historical (Caused by ProxyError('Cannot connect to proxy.', timeout('_ssl.c:835: The handshake operation timed out',)))], attempts 0of 500


Diagnosis: This could also be due to the network issues causing delays in the communication between the your system and the CDS.  Therefore we recommend to try this solution first
