A client error (SignatureDoesNotMatch) occurred when calling the CreateBucket operation: The request signature we calculated does not match the signature you provided. Check your key and signing method.

I have been able to run my s3 commands just fine. But today when I try from my local PC (OSX, command-line cli calls) as I always have when testing, I get:

aws s3api create-bucket --bucket our-bucket-name --region us-west-2 --create-bucket-configuration LocationConstraint=us-west-22

and it is bombing today out of the blue with A client error (SignatureDoesNotMatch) occurred when calling the CreateBucket operation: The request signature we calculated does not match the signature you provided. Check your key and signing method.

what could cause this all of a sudden? I rebuilt a previous Travis build using some AWS credentials I had addd as enviornment variables in Travis and that build still works with the asw credentials I specified, but I've not had to specify my AWS credentials locally for aws cli calls or if I did, then I don't remember but regardless this was working fine yesterday.

Here's another call that was working just fine up till now

aws s3api head-bucket --bucket mayfield-gizmo-react-web-admin-wa-19

A client error (403) occurred when calling the HeadBucket operation: Forbidden
So why was I able to make calls fine without specifying credentials locally, but now it's complaining all of a sudden?

I don't know what it was but I reset my credentials locally and it's working. No idea why the hell it would just stop using the credentials that are already set locally which I guess I did do at some point:

This error occurred when you AWS credential set using environment variables And the key has special characters in my case "/" Related issue: https://github.com/aws/aws-cli/issues/602

Thank you, worked like a charm!

I got a special character too a "+" plus symbol. Generated other key without special charactes and it is working again! Thanks

Worked for me :D TRY THIS: Just had this happening to me and was a result of my system time being off by too much even though it did not report that. Ran ntpdate against pool.ntp.org and fixed this problem for me.

show me how you did it

My AWS credentials are from STS assume role. How do I make sure it does not generate a special character?

Well done

I ran into this issue a few weeks ago and finally found this post! Resetting the AWS SECRET ACCESS KEY helped with this issue and I am now able to successfully run ./bin/db/update_cognito_user_ids THANK YOU!🙏🏾
