S3 File upload not working on ca-central-1

[tmora8702]

Hi.

We're currently facing an issue when uploading files into an S3 bucket:

`AmazonClientException:

com.amazonaws.services.s3.model.AmazonS3Exception: The request signature we calculated does not match the signature you provided. Check your key and signing method. (Service: Amazon S3; Status Code: 403;
Error
Code: SignatureDoesNotMatch; Request ID: WFR22B0BBBH8JH5R; S3 Extended Request ID: KvP1tVsl2vVn1blrkGHZNFGvFyyuDhSoFcsbUSuUWp3g9T/Ou2WoLg9qcqaF2dn8oLVaM3VaZJ0=; Proxy: null)`

Uploading the same file on different regions work properly, but even using same bucket configs it fails on ca region; no clue about what could be the issue.

Any hints about it?.

Thanks!
