Python: connexion TLS/SSL a été fermé

Question

Mon code

conn = __get_s3_connection(s3_values.get('accessKeyId'), s3_values.get('secretAccessKey')) 
key = s3_values.get('proposal_key') + proposal_unique_id + s3_values.get('proposal_append_path') 
request = urllib2.Request(conn.generate_url(s3_values.get('expires_in'), 'GET', bucket=s3_values.get('bucket'), key=key)) 
request.add_header('Accept-encoding', 'gzip') 
response = urllib2.urlopen(request) 

L'URL ressemble https://production.myorg.s3.amazonaws.com/key/document.xml.gz?Signature=signature%3D&Expires=1349462207&AWSAccessKeyId=accessId

Cette méthode fonctionnait très bien jusqu'à 1 heure de retour, mais quand je lance le même programme, il jette

    raise URLError(err) 
urllib2.URLError: <urlopen error [Errno 6] _ssl.c:503: TLS/SSL connection has been closed> 

Quelle pourrait être la raison? Comment puis-je éviter cette situation?

Cela était dû à une connexion Internet intermittente. Résolu sur son propre
