尝试使用 Python PySFTP 模块连接到远程服务器时出现 WinError 10060 错误

Question

我正在尝试使用以下代码连接到远程服务器并列出路径中的文件：

import pysftp

myHostname = "myhostname.com"
myPort = <someportnumber>
myUsername = "<valid username>"
myPassword = "<valid password>"

cnopts = pysftp.CnOpts()
cnopts.hostkeys = None

with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts= cnopts, port=myPort) as sftp:
    print("Connection succesfully established ... ")

    sftp.chdir('/logs/dev')

    # Obtain structure of the remote directory
    directory_structure = sftp.listdir_attr()

    # Print data
    for attr in directory_structure:
        print(attr.filename, attr)

但是当我运行它时，它无法建立连接。它抛出以下异常：

Traceback (most recent call last):
  File "c:/Users/611841191/Documents/SFTP File Download/SFTPFileDownload.py", line 11, in <module>
    with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts= cnopts, port=myPort) as sftp:
  File "C:\Users1841191\AppData\Roaming\Python\Python38\site-packages\pysftp\__init__.py", line 140, in __init__
    self._start_transport(host, port)
  File "C:\Users1841191\AppData\Roaming\Python\Python38\site-packages\pysftp\__init__.py", line 176, in _start_transport
    self._transport = paramiko.Transport((host, port))
  File "C:\Users1841191\AppData\Roaming\Python\Python38\site-packages\paramiko\transport.py", line 415, in __init__
    raise SSHException(
paramiko.ssh_exception.SSHException: Unable to connect to <myhostname.com>: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time or established connection failed because connected host has failed to respond

任何人都可以帮助我解决为什么抛出此异常的原因，因为我尝试使用其他远程服务器并且代码似乎对他们来说工作正常？该代码仅针对一个特定的远程服务器抛出异常。

如果您的代码无法使用某种协议（在本例中为 SFTP）连接到某处，首先要测试的是，您是否可以使用来自同一台机器的任何现有 GUI/commandline 客户端使用相同的协议进行连接运行你的代码。

如果这也不起作用，则您没有编程问题，而是简单的网络连接问题。
