Database Connection Issue on Production (SQLSTATE[HY000] [1130] Host 'localhost' is not allowed to connect to this MariaDB server)

Hello everyone,

I have a Laravel project running in production, and users are actively using it. However, whenever I log out, I encounter the following database error:

SQLSTATE[HY000] [1130] Host 'localhost' is not allowed to connect to this MariaDB server

This error seems to come from my AppServiceProvider.php file. Here’s my code:

if (Schema::hasTable('permissions')) { // This line shows a red error in production
    View::share('permissions', Permission::all());
}

if (Schema::hasTable('general_settings')) {
    View::share('general_logo', GeneralSetting::where('name', 'logo')->first());
    View::share('site_title', GeneralSetting::where('name', 'Site Title')->first());
}

I am worried about upcoming errors and potential database connection issues. Since this is happening in production, I need a stable solution to prevent further problems. Has anyone faced this issue before? How can I fix this without causing downtime for users? Any help would be greatly appreciated.
