**Your software**
My Mautic version is: 5.1
My PHP version is: 8.2.20
My Database type and version is: Maria db
**Your problem**
My problem is: Cant’ get Amazon ses to work.
I get the following message when I wnat to test the connection:
_Unable to send an email: 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. (code InvalidSignatureException)._
However, scheme (ses+api), region, name and secret key etc. are all correct.
These errors are showing in the log: none
Steps I have tried to fix the problem: followed Joey’s walkthrough, [Mautic 5 Composer install simplified – Joey Keller](https://joeykeller.com/mautic-5-composer-install-simplified/) with a fresh install. Also have the plugin: [GitHub - pabloveintimilla/mautic-amazon-ses: Mautic 5 plugin, provides Amazon SES as an email transport and callback to process bounces](https://github.com/pabloveintimilla/mautic-amazon-ses)

Please check, if this could be the reason: [Connection with Amazon SES API won't work (error403), when the defined password contains a "/" · Issue #12256 · mautic/mautic · GitHub](https://github.com/mautic/mautic/issues/12256)
