Greetings!

Apologies for the delayed response, as I've been out of the office.

Thanks for reaching out! Our team will take a look at reboot the server as 
necessary.

In the meanwhile, you might consider using the Python boto3 library to download 
the data directly from S3:

    from datetime import datetime

    import boto3
    import botocore
    from botocore.client import Config
    from metpy.io import Level2File

    s3 = boto3.resource('s3', config=Config(signature_version=botocore.UNSIGNED,
                                            user_agent_extra='Resource'))
    bucket = s3.Bucket('noaa-nexrad-level2')
    d = datetime(2020, 5, 3, 23)
    station = 'KTLX'

    prefix = f'{d:%Y}/{d:%m}/{d:%d}/{station}/{station}{d:%Y%m%d_%H}'
    for obj in bucket.objects.filter(Prefix=prefix):
        print(obj.key)
        break

    f = Level2File(obj.get()['Body'])

Cheers!
