CDSAPI Recovering from connection error (Caused by SSLError)



I was able to get this working last week but not for this week anymore. Keep getting this error WARNING Recovering from connection error [HTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /api/v2/resources/reanalysis-era5-single-levels (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)')))], attemps 3 of 500

Below is my code.

               "variable": "precipitation",
               "product_type": "reanalysis",
               "year": str(d.year),
               "month": str(d.month),
               "day": str(,
               "time": "00:00",
               "area": ["40","60","-60","180"],
               "format": "grib"
           }, "rr_" + yy + mm + dd + ".grib")

Is there specific maintenance or any period of the week that it may not be working well? Appreciate any assistance. Thank you.
