Connect timeout after ~30 minutes of activity

[sy6sy2]

Context: A Python script that use pywinrm to open a WinRM session on a remote Windows host. Once the WinRM session is open the script send continuously PowerShell command to explore the remote hard drive and retrieve each directory listing.

I use ntlm transport. My client is macOS and the remote Windows host is Windows 7 SPI with Powershell 5.1.

Problem: After ~30 minutes of run the run_ps that I use to get the directory listing failed with this error message:

ConnectTimeout(MaxRetryError("HTTPConnectionPool(host='192.168.1.42', port=5985): Max retries exceeded with url: /wsman (Caused by ConnectTimeoutError(<urllib3.connection.HTTPConnection object at 0x7f06380c1430>, 'Connection to 192.168.1.42 timed out. (connect timeout=30)'))

I can reproduce this issue each time.

Is the WinRM session has a kind of maximum time? I don't think so...

This is not an idle timeout issue because the last working run_ps command is only 1 second before the one that produce the time out issue.

Thank you for the help.
