Temporarily disable user role login and replace with message

Is there a simple way to temporarily stop a user role logging in with wordpress?

For example, if I have a user role called media, how can I block them from logging in?

I would like a custom message to appear on the website, for example like 'Site undergoing maintenance'

So it looks like this:

The reason why, is because my website is completely locked down from the public using this function...

// LOCK DOWN
add_action('get_header', 'wpq_member_only_site');
function wpq_member_only_site() {
    // logged in users or visits to a specified page are allowed
    if ( !is_user_logged_in() ) {
        
        $redirect_after_login = get_home_url();
        
        // the URL where login/registration takes place
        $login_url = wp_login_url( $redirect_after_login );
                
        // redirect visitors
        wp_redirect( $login_url, 302 );
        exit;
    }
}

But I need to do some maintenance and I'm after a simple way to lock all users out that are the role media.

This is because I wan't administrators and editors to still have access, but not media.

• I created a simple plugin that will allow you to do this without messing around with code. The message displayed to disabled users is also filterable. wordpress.org/plugins/disable-users – jaredatch Commented Aug 29, 2013 at 2:17
• If you want to use the ready-made plugin for a temporary block of certain user's accounts then the User Blocker WordPress plugin is a useful solution for you. https://wordpress.org/plugins/user-blocker/ – Mary Martin Commented Feb 11, 2021 at 5:31

With a some digging and learning, I managed to combine various help and create these 2 functions...

// MAINTAINANCE MODE
function site_maintenance() {
    if ( current_user_can('media') || current_user_can('genpo') ) {

       $logout_url = wp_login_url().'?mode=maintainance';
       wp_logout();
       wp_redirect( $logout_url, 302 );

    }     
}
add_action('get_header', 'site_maintenance');

// CUSTOM LOGIN MESSAGES
function my_login_message() {

    if( $_GET['mode'] == 'maintainance' ){
        $message = '<p class="message"><b>Site undergoing maintainance.</b></p>';
        return $message;
    }

}
add_filter('login_message', 'my_login_message');

Add in a check for a capability that admins and editors share:

add_action( 'get_header', 'wpse81659_maintenance' );
function wpse81659_maintenance() {
    if ( ! current_user_can( 'publish_pages' ) || ! is_user_logged_in() )
        die( 'Site undergoing maintenance' );
}

add_filter( 'authenticate', 'restrict_media_role_authenticate', 99 );
function restrict_media_role_authenticate( $user, $username, $password ){
    if ( in_array( 'media', (array) $user->roles ) ) {
        return new WP_Error( 'denied', "Site undergoing maintenance." );
    }
    return $user;
}
