Hi, The request on the cds didn’t reach the server for “seasonal-original-single-levels” data types.
Error message : “WARNING:multiurl.http:Recovering from connection error [(‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’))], attemps 1 of 500”
For other data types like ERA5 or seasonal-montly I don’t have this issue.
Tanks,
Frédéric Gayrard

Hi Frederic. Can you share the exact request that you’re having an issue with? And also another one that you’re not having an issue with?

Thanks,

Here is an exemple of a failed query and one that is ok.
Note that the failed query doesn’t appear in the climate data store dashbord (Climate Data Store)

Thanks Frederic. This confirms what I was expecting. It’s a bug we’ve seen internally as well but we thought external users were unaffected. We think it relates to the size of the request dictionary. Once it exceeds a certain number of characters you can get this problem, but not everybody sees it. We are investigating.

Luke.
