> This is a known issue with boto and only affects uploads to S3 buckets outside of the standard US location (in my case {{eu-west-1}}).
> The issue is reported on boto side as:
> https://github.com/boto/boto/issues/2207
> A work around is mentioned by user {{anna-buttfield-sirca}} which basically reconnects the boto S3 connection to the corresponding location.
> I will provide a PR implementing the work around, since a resolution of the issue on the boto side seems unlikely.
