Got WinRMOperationTimeoutError when using python winrm library to call a local powershell script on a windows server

[condescendent]

I am trying to user winrm library to call a local powershell script to stop MS SQL server engine service from a Lambda function. I got the below error. The connection was established successfully.

The log for establishing connection:

Establishing connection to 10.251.3.22

Connection established

The error I got after the above two logs.

[ERROR] WinRMOperationTimeoutError
Traceback (most recent call last):
File "/var/task/lambda_function.py", line 237, in lambda_handler
result = session.run_ps('c:\shutdown_script.ps1')

rs = self.run_cmd('powershell -encodedcommand {0}'.format(encoded_ps))
File "/var/task/winrm/init.py", line 39, in run_cmd
shell_id = self.protocol.open_shell()

res = self.send_message(xmltodict.unparse(req))
File "/var/task/winrm/protocol.py", line 265, in send_message
