и когда я пытаюсь загрузить файл размером 15 МБ, он выдает исключение EndPointNotFoundException ниже:

Сообщение об исключении:

There was no endpoint listening at "MY SERVICE URL" that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Исключение:

The remote server returned an error: (404) Not Found.
