AWS Lambda Python Function using boto3 for S3 get_object fails intermittently with a timeout – Amazon Web Sevices

I am using python 3.9 and boto3 to issue the following statements from a lambda function.
The function works 90% of the time. But every now and then it stops working for a few hours.
The lambda function times out.
See Cloud watch log below.
The lambda timeout is set to 20 seconds…when it works the s3 file reads in about three hundredths of a second.
The get_object function doesn’t look like it times out…it just hangs forever.
All the exceptions in the try are me just trying to trouble shoot…The function never prints any of the except prints to the log.

Any Ideas why S3 just drops for hours at a time and why the boto3 get_object never times out?

Thanks for any help!

config = boto3.session.Config(connect_timeout=5, read_timeout=5, retries={'max_attempts': 0})
s3 = boto3.client('s3',config=config,aws_access_key_id='XXXX',aws_secret_access_key='XXXX')
file = GetS3file("index.html")


def GetS3file(filename):
    global responseout
    responsefile=""
    try:
        print("trying s3 get_object:samplebucket:"+filename)
        response=s3.get_object(Bucket='samplebucket',Key=filename)
        print("After S3 get_object")
        responsefile=response['Body'].read().decode('utf-8')
        responsefile=str(responsefile)

    except botocore.exceptions.ClientError as error:
        print("Boto Exception:"+str(error))
        responsefile="Page Not Found: "+filename+"  b-error:"+str(error)
    except botocore.exceptions.ReadTimeoutError as error:
        print("Boto read timeout Exception:"+str(error))
        responsefile="Page Not Found: "+filename+"  b-error:"+str(error)
    except botocore.exceptions.ConnectTimeoutError as error:
        print("Boto connect timeout Exception:"+str(error))
        responsefile="Page Not Found: "+filename+"  b-error:"+str(error)
    except Exception as e:
        print("Exception:"+str(e))
        responsefile="Page Not Found: "+filename+"  error:"+str(e)
    return responsefile

I tried to access a file in a bucket using python and and boto3.get_object. I was expecting it to read and it does 90% of the time. But sometimes it stops working for as long as a few hours. and then it starts working again for no discernable reason. I tried logging exceptions and lowering the timeout on the get_object call so the get method will timeout and fail so I can get an error message but it still doesn’t timeout in the indicated time.
