Error "The request signature we calculated does not match the signature you provided" Connecting to Athena When Server Contains Uppercase Letters

Data pubblicazione: Feb 25, 2026
Descrizione

When attempting to connect or refresh an Athena extract that uses a server address that contains uppercase letters, the following error occurs: 


TableauException: [JDBC Driver]The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details. (Service: AmazonAthena; Status Code: 400; Error Code: InvalidSignatureException; Request ID: [...]) System error."

Cause

A change on the Athena side requires the server address be in lowercase letters.
Risoluzione
Option 1 Change the server (Athena.eu-west-1.amazonaws.com) to start with a lower case letter (athena.eu-west-1.amazonaws.com)

Option 2 Change the server (Athena.eu-west-1.amazonaws.com) to include the region (athena.eu-west-1.amazonaws.com;AwsRegion=eu-west-1;)
Risorse aggiuntive

If you recently changed your Access Key, or this is the first time you've tried to refresh, it may be a special character. See the following KB article The request signature we calculated does not match the signature you provided." When Connecting to Amazon Athena
