Я получаю следующую ошибку: (index):24 POST https://goldengates.club:3000/api/transact net::ERR_SSL_PROTOCOL_ERROR

(anonymous) @ (index):26 при попытке отправить почтовый запрос со стороны клиента на мой бэкэнд API. Я открыл порт 3000 с помощью express, чтобы принимать запросы на конечной точке с именем api / transact, куда клиент отправляет данные. Проблема, похоже, связана с моим текущим ssl, но я не знаю, в чем конкретно проблема.
