External storage > can't manage to add any kind

Hi,
Nextcloud 19.0.5
Debian 10

Impossible to add external storage through this extension (FTP(S), SFTP, SMB = NOK)

I try the connection to a NAS which is OK since I tested these protocl which are OK

I checked my php.ini and config.php files, there are OK

Any ideas ?
many thanks in advance

Which protocol are you using?

I tried FTP FTPS SFTP, SMB and WEBDAV.

Hi,
Is there anybody in there … :sunglasses: ?

UP :roll_eyes:
And thanks in advance.
