Scope or Signature not working

[HenriqueOtsuka]

Hey guys,

I've generated the scope and the signature using the python script and hardcoded into my NGINX to test, but AWS response says that the signature expected doesn't match The request signature we calculated does not match the signature you provided. Check your key and signing method

I'm stucked into this somedays and I really don't know what more I can do.

I'm using ./script -k my-aws-secret-key -r my-aws-region -s my-aws-service, it returns the right scope and the signature and the I'm copying and pasting into nginx to use it.

location /test {
aws_access_key AKIAEXAMPLETEST;
        aws_s3_bucket my-test-bucket;
        aws_key_scope 20230630/us-east-1/s3/aws4_request;
        aws_signing_key SOMERANDOMVALUE=;
        aws_sign;

        proxy_pass http://my-test-bucket/my-test-file.mp4
}

Any ideas?

Do you have debug nginx logs to share for the entire request, and response?

[HenriqueOtsuka]

Hmmm, no I don't have any other logs.

This error is the only thing I have.

Is your proxy pass url of the format bucket-name.aws-region.s3.amazonaws.com ? I had the same problem and just reduced it to bucket-name.s3.amazonaws.com to solve it.
