Push Notification not working after move my Laravel code from one server to another

Please help me. After moved, my Laravel project from one server to another push notification is not working. I am using Firebase for push notification

In log this response is coming:

[2021-10-28 11:11:58] local.DEBUG: {"connection":null,"queue":null,"chainConnection":null,"chainQueue":null,"delay":{"date":"2021-10-28 11:12:03.901592","timezone_type":3,"timezone":"UTC"},"chained":[]}

After moving code to another server I ran these commands first:

composer dumpautoload
php artisan config:cache
