Hello
When I want to backup via command line everything works fine via command
php artisan backup:run
or
php artisan backup:run --only-db
or
php artisan backup:run --only-files
But when I execute the command from the controller, I have the following error:
Backup failed because: The dump process failed with exitcode 2 : Misuse of shell builtins : mysqldump: Got error: 2004: "Can't create TCP/IP socket (10106)" when trying to connect
note: this error not shown with php artisan backup:run --only-files command
please any help!!
