Hi everyone,

I am trying to download the ERA5 pressure level data using the following python script:

import cdsapi
c = cdsapi.Client(timeout=600,quiet=False,debug=True)
c.retrieve('reanalysis-era5-complete',{
    'class':'ea',
    'date':'20190101/to/20190110',
    'area':'65/-20/25/40',
    'expver':'1',
    'levtype':'sfc',
   'param':'msl/sp/skt/2t/10u/10v/2d/z/lsm/sst/ci/sd/stl1/stl2/stl3/stl4/swvl1/swvl2/swvl3/swvl4', 
    'stream':'oper',
    'time':'00:00:00/03:00:00/06:00:00/09:00:00/12:00:00/15:00:00/18:00:00/21:00:00',
    'type':'an',
    'grid':"0.25/0.25",

},'ERA5-20190101-20190110-sfc.grb')

However, I always got the error:

2022-04-21 14:48:53,480 DEBUG CDSAPI {'full_stack': False, 'timeout': 600, 'url': u'https://cds.climate.copernicus.eu/api/v2', 'verify': True, 'retry_max': 500, 'ss': True, 'sleep_max': 120, 'delete': True}

It seems that the request is not able to send to the sever because of the delays in communication. Do you have some suggestions to solve it?

Cheers
