这表示上传过程超时了。您可以尝试减少文件的大小或分批上传。此外，您还可以通过以下代码示例更改超时设置：

import requests

url = "https://developer.api.autodesk.com/oss/v2/buckets//objects/"

access_token = ""

headers = {
    "Authorization": "Bearer " + access_token,
    "Content-Type": "application/octet-stream"
}

with open('', 'rb') as f:
    data = f.read()

response = requests.put(url, headers=headers, data=data, timeout=60)

if response.status_code == requests.codes.ok:
    print("File Uploaded Successfully!")
else:
    print("Error", response.reason)

在此示例中，“timeout”参数设置为60秒，您可以根据自己的需求进行调整。
