WPvivid SFTP upload fails

    Hello,

    I have an SFTP backup upload problem with WPvivid.

    Environment:

    • WordPress hosted on o2switch
    • PHP 8.1.34
    • SSH2 PHP extension 1.11.1
    • WPvivid 0.9.133
    • SFTP server: eros.usbx.me:22
    • Server: OpenSSH 10.0p2 / Debian 13

    WPvivid successfully creates the backup locally, but fails when uploading it to SFTP with:

    “The connection failed because of incorrect credentials or server connection timeout.”

    I have tested the same connection from the same o2switch server:

    • OpenSSH sftp → connection and file upload successful
    • PHP ssh2_connect() → successful
    • PHP ssh2_auth_password() → successful
    • PHP SSH2 SFTP upload → successful
    • XCloner → same SFTP server → backup and upload successful

    Therefore, the SFTP server, credentials, port 22, firewall and PHP/SSH2 environment are working correctly.

    I also noticed that WPvivid includes its own phpseclib implementation:

    vendor/phpseclib/phpseclib/phpseclib/Net/SFTP.php
vendor/phpseclib/phpseclib/phpseclib/Net/SSH2.php

    Could you please investigate whether there is a compatibility issue between WPvivid’s bundled phpseclib/SFTP implementation and the current OpenSSH 10 server?

    The fact that XCloner works successfully with the exact same SFTP destination suggests that the problem is specific to WPvivid.

    I can provide additional logs or perform further tests if needed.

    Best regards,

    I have a similar problem with WPvivid Backup Plugin since today’s update. DB backups, incremental and manual, fail across the board.

    This affects sftp and even local backups in my case.

    Backup: Failed. /home/wordpress/www.xyz.com/wp-content/wpvividbackups/www.xyz.com_wpvivid-35e2d7261e457_2026-09-01-14-32_backup_db.zip not found. The file might has been moved, renamed or deleted. Please back it up again.

    PHP-Logfile says:

    [01-Sep-2026 09:44:17 UTC] PHP Warning: filesize(): stat failed for /home/wordpress/www.xyz.com/wp-content/wpvividbackups/www.xyz.com_wpvivid-9b0ab28e6f508_2026-09-01-11-40_backup_db.zip in /home/wordpress/www.xyz.com/wp-content/plugins/wpvivid-backup-pro/addons2/backup_pro/class-wpvivid-sftpclass-addon.php on line 707

    .sql-dump-files part001 and part002 get generated, then the part001.zip, and then they disappear and the error occurs.

    Maybe this is connected.
