Nginx не удалось найти js файлы реакции docker контейнера

Question

У меня на хосте работает nginx. Он перенаправляет в контейнер docker на порт 5000 при доступе к / admin и при записи / перенаправляет на порт 80.

Хотя перенаправление работает, файлы js и css не загружаются контейнером реакции. Я вижу, что заголовок страницы меняется на заголовок контейнера React, но на вкладке сети в Google отображается 404 для всех файлов js.

Что мне не хватает?
