AWS Authentication not working in region eu-central-1

[joakimcs]

Excellent library - works fine in eu-west-1 and default region. Does not work in eu-central-1, and fails with the following error message:

ec2-expire-snapshots: ERROR: describe_snapshots: AuthFailure: AWS was not able to validate the provided access credentials at /usr/bin/ec2-expire-snapshots line 186.

Have tried to locate possible fixes, and suspect a pointer to the solution might be found here: alestic/ec2-consistent-snapshot#47

It's to do with eu-central requiring requests be signed with the v4 signature. This is not currently supported in the underlying Perl EC2 module: https://rt.cpan.org/Public/Bug/Display.html?id=99779

A possible fix with code is on the bottom on the page.

I'm no a Perl programmer myself, so sorry I can't contribute. Hope this is of help!

Found the same issue with ec2-consistent-snapshot:
alestic/ec2-consistent-snapshot#47 (comment)

So replaced the code:

line: 113-118

my $ec2 = Net::Amazon::EC2->new(
    ((! $use_iam_role) ? (AWSAccessKeyId  => $aws_access_key_id,) : () ),
    ((! $use_iam_role) ? (SecretAccessKey => $aws_secret_access_key) : () ),
    ($ec2_endpoint ? (base_url => $ec2_endpoint) : ()),
    # ($Debug ? (debug => 1) : ()),
);

with:

my $ec2 = Net::Amazon::EC2->new(
    ((! $use_iam_role) ? (AWSAccessKeyId  => $aws_access_key_id,) : () ),
    ((! $use_iam_role) ? (SecretAccessKey => $aws_secret_access_key) : () ),
    signature_version => 4,
    ($region ? (region => $region) : ()),
    ($ec2_endpoint ? (base_url => $ec2_endpoint) : ()),
    ($Debug ? (debug => 1) : ()),
);
