What type of error are you seeing?
Timed out
If
...
the error message
...
mentions 'timed out' like the example below:
WARNING Recovering from connection error [HTTPSConnectionPool(host='cds.climate.copernicus.eu', port=443): Max retries exceeded with url: /api/v2/tasks/7b4e735b-5a79-4913-bbcb-cebc0c65b420 (Caused by ConnectTimeoutError(<urllib3.connection.VerifiedHTTPSConnection object at 0x7f81056e8940>, 'Connection to cds.climate.copernicus.eu timed out. (connect timeout=60)'))], attempts 12of 500 |
Diagnosis: This is

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

proxy’ like the example below:
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
Solution: 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) |
If the issue continues you will need to check that the ports required by the CDS are open on your firewall (i.e. https, 443)
