Hi all

We broke our website yesterday, as one of the WP plugins needed a newer PHP version.

We took a back up just before starting the process, and that saved correctly.

However, the backup restore fails with an authentication error. Below is the complete output

root@nginx-php-fastcgi /etc# duplicity --archive-dir=/var/cache/duplicity --s3-unencrypted-connection s3://our_s3_url /tmp/tklbam-NvXy2w

    'Check your credentials' % (len(names), str(names)))

Has anyone come across this issue before?

Many thanks
