Err_Invalid_response

The file %plesk_dir%admin\logs\php_error.log contains the following record at the same time:

CONFIG_TEXT: PHP Fatal error: Maximum execution time of 300 seconds exceeded in C:\Program Files (x86)\Plesk\admin\htdocs\domains\databases\phpMyAdmin\libraries\classes\Dbi\DbiMysqli.php

Cause

The error occurs because of a huge file and the restoration process fails with timeout.

Resolution

Starting from Plesk 12.5, it is possible to import databases via Plesk.

Browse to Home > Domains > example.com > Databases and use importing functionality:

If it does not fit some needs proceed with the following solutions.

Solution 1

Increase the 'ExecTimeLimit' value:

Linux:

  1. Login to the server over SSH

  2. Create the file config.inc.php.
    For Plesk Onyx and Plesk Obsidian below 18.0.30:

    # cp -p /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.default.php /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/config.inc.php

    For Plesk Obsidian 18.0.30 and above:

    # cp -p /usr/local/psa/phpMyAdmin/libraries/config.default.php /usr/local/psa/phpMyAdmin/config.inc.php

  3. Increase the value of $cfg['ExecTimeLimit'] in config.inc.php created on step 2:

    CONFIG_TEXT: $cfg['ExecTimeLimit'] = 3600;

  4. Increase the settings in /etc/sw-cp-server/config to avoid '504 Gateway Timeout' error:

    CONFIG_TEXT: fastcgi_read_timeout 3600;
    fastcgi_send_timeout 3600;

  5. Restart sw-cp-server:

    # service sw-cp-server restart

Note: if the issue still persist, the browser cache should be cleared.

Windows:

  1. Login to the server over RDP.

  2. Create the file config.inc.php
    For Plesk Onyx and Plesk Obsidian below 18.0.30:
    Copy the content of %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\libraries\config.default.php to %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\config.inc.php.

    For Plesk Obsidian 18.0.30 and above:
    Copy the content of %plesk_dir%phpmyadmin\libraries\config.default.php to %plesk_dir%phpmyadmin\config.inc.php.

  3. Increase the value of $cfg['ExecTimeLimit'] in config.inc.php created on step 2:

    CONFIG_TEXT: $cfg['ExecTimeLimit'] = 3600;

Solution 2

Upload the database via command prompt:

Linux:

  1. Login to the server over SSH.

  2. Upload the database dump to the server (any of the convenient ways).

  3. Restore the database:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -uadmin db_name < /path/to/database_dump

Windows:

  1. Login to the server over RDP.

  2. Upload the database dump to the server.

  3. Restore the database:

    C:\> "%plesk_dir%MySQL\bin\mysql.exe" -u DBUSER -p******** -P 3306 DATABASENAME < .\path\to\mysql_backup.sql
