Amazon SES Status - SignatureDoesNotMatch

edited February 17 in Troubleshooting


I was working with Sendy from the version 4 with Amazon SES and recently bought the version 5, in the release 5.0 the Amazon SES does not work, I deleted the IAM user and created a new one, added permissions for both SNSfull and SESfull, re-added the domain and emails in SES until the verified status appears. I also make some tests in AWS and it is working fine. My sending limit is 50,000. Everything seems ok, but I always received the status error Error: SignatureDoesNotMatch in Sendy. I have CentOS 7 and update the date to my zone NTP.

I also upgraded to the latest 5.2 version as usual in Sendy and it doesn't work.

Many thanks

    Your server clock is not synced with NTP.

    Run the following command to sync your server's clock with NTP:

    sudo /usr/sbin/ntpdate

    Hi Ben.

    The problem was that i have CentOS 7.4 as it comes with chronyd, this version have a bug, the time was 5 minutes on back. The solution was to delete chronyd and install ntpd. then sync the server clock with NTP.

    Many thanks
