websockets.exceptions.ConnectionClosedError: code = 1006 (connection closed abnormally [internal]), no reason

Есть вебсокет соединение,по которому клиент передаёт файлы. На сервере происходит обработка файлов с помощью aiofiles. Также уходят запросы на гугл апи. Ответ отправляется клиенту.

Однако получаю ошибку - websockets.exceptions.ConnectionClosedError: code = 1006 (connection closed abnormally [internal]), no reason

Когда работаю с файлами - ошибка вылетает сразу же. Когда работаю с гугл апи - спустя какое-то время.

Так понимаю, связано с тайм-аутом каким-то?
