2020-03-05T04:29:51.929460+00:00 app[web.1]: Server listening on: http://localhost:5967

Я предполагаю, что вы связали свой порт с переменной окружения $PORT, предоставленной Heroku. Я предполагаю, что порт 5967. Ваша программа пытается получить доступ к 3306. Вы, наверное, где-то определили этот порт. Это на Героку не возможно.

Heroku позволяет связывать только один порт с номером порта, определенным Heroku.
