Can you share your manifest without the credentials ? Also, did you upload
release yml or release tarball ?

Hi,

I am trying to upgrade my cf to v251, when I ran bosh deploy, it gave
error during build
pack upload to blobstore after compilation:
caused by: SignatureDoesNotMatch: The request signature we calculated does
not match the
signature you provided. Check your AWS Secret Access Key and signing
method. For
more information, see REST Authentication and SOAP Authentication for
details.

Later when I tried to deploy again, it is giving me:
Failed to download S3 object, code 1, output: '', error: '2017/07/05
17:36:10
performing operation get: ServiceUnavailable: The server is temporarily
unavailable.
Please try again later

I tried aws cli s3 ls and was able to list folders there using the
credentials.

What could be causing this?
