This is on EC2 talking to S3, so maybe related to <<issue 20>>, perhaps a boto issue not django-storages.

This happens regularly but not consistently for us, both on initial upload (browser->ec2->s3) and also using django-imagekit to generate cached thumbnails (so just ec2->s3). Files are typically 50k-500k. Typically will go through after a few manual retries by the user.

    I had something similar to this issue a few years ago when first using django-storages. My solution was to set a longer querystring expiry parameter (eg 600, ie, 10 mins) rather than the default 60).


    I'm not sure this is the best way to do it, but it worked for me

    Are you using querystring auth? Does the suggestion that Steve Jalim mentioned work for you?

    I'm afraid something like this would best be solved by sub-classing the S3BotoStorage class and supporting retries to a level sufficient for your application. Or supporting retries somehow within your application code.
