Empty file not download

Hello
Definitely I keep having problems with Owncloud.
Here are the latest mistakes

Where does the problem come from?

Web server: Ovh mutualisé

Database: MYSQL v.5.6

PHP version: 7.3

ownCloud version: 2.8.1 (build 4157)

Storage backend (external storage):

Client configuration

Client version: 10.7.0.4

Can you download the same file in the web UI?

Could you check the owncloud.log for related errors? Maybe post a few lines…

Looks like this error message in the desktop sync client:

    <message>
        <location filename="../src/libsync/propagatedownload.cpp" line="727"/>
        <source>The downloaded file is empty despite the server announced it should have been %1.</source>
        <translation>Le fichier téléchargé est vide bien que le serveur indique que sa taille devrait être de %1.</translation>
    </message>

Similar issue points to a server misconfiguration:
