Docker, laravel-websockets, ошибка "Failed to connect to Pusher"

Разворачиваю проект laravel с пакетом beyondcode/laravel-websockets с помощью Docker. Проблема в том что в WebSockets Dashboard подключение проходит успешно. Но при попытке отправить broadcast событие возникает ошибка "Failed to connect to Pusher". Не могу понять в чем дело. Поиск в google результатов не дал.

Laravel v8.83.14

Docker Desktop + WSL 2 + Ubuntu 20.04

Когда я разворачиваю с помощью OpenServer и запускаю php artisan websockets:serve все хорошо работает. Проблема именно в настройки Docker'a
