Error when accessing backup via reverse proxy

[TobiasP]

When accessing a backup in backup-manager in a user subscription via a reverse proxy (eg. plesk panel is called as localhost:8443) I get following error:

Internal error: Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File \'clients\' not found ', 'stderr' => '', )).
Message Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File \'clients\' not found ', 'stderr' => '', )).
File Connector.php
Line 227
Type PleskPMMResponseException

this happens when I try to download the backup and also when clicking on the backup name.
These are the apache settings for the reverseproxy domain:

SSLProxyEngine On
AllowEncodedSlashes On
<Location />
ProxyPass https://localhost:8443/
ProxyPassReverse https://localhost:8443/
</Location>
