nginx: ошибка ограничения скорости в теле запроса nextcloud

Я запускаю nextcloud за nginx, действующим как обратный процесс, выполняющий завершение края tls. Когда я синхронизируюсь, я получаю следующую ошибку в nginx:

Как я могу избежать этой ошибки? Помимо настроек по умолчанию для nginx, я уже увеличил лимит размера тела запроса:

 client_max_body_size 2G;

Размер синхронизированных видеороликов составляет около 20 МБ каждый.
