----------------------------------------
I'm having the same problem and have some additional information. I send the
following curl call and get the following error:
curl -i -X GET -H 'x-ms-version: 2012-02-12' -H 'Accept-Encoding: gzip,deflate'
-H 'X-LC-Request-ID: 140216384132432' -H

It took me a while but I found the following page on the Azure site:
https://docs.microsoft.com/en-us/rest/api/storageservices/azure-storage-services-versions-2015-07-08-and-earlier
Specifically:
{quote}
A request made via a SAS is processed according to which service version was
used to generate the SAS. Versions 2013-08-15 and 2012-02-12 include a
versioning parameter (SignedVersion, or sv), which specifies which version to
use to authenticate and execute the SAS request.
Version 2012-02-12 and later
Requests with Shared Access Signatures (SAS) generated using version 2012-02-12
or later require the SignedVersion (sv) parameter. SignedVersion indicates the
service version used for authentication and authorization and for calling the
API operation. If the x-ms-version header is passed on the request, it is
ignored; only the SignedVersion (sv) parameter determines the service version
to use to process the request made via the SAS{quote}
In other words, an sv= parameter needs to be added that matches the
x-ms-version, and it's not optional for x-ms-version: 2012-02-12.
Thanks.
