Thanks for reaching out, @ammu440!

It looks like you're encountering a complex issue with the check_esxi_hardware plugin in Nagios. Based on your error logs, this seems to be a connection issue when your script tries to communicate with the ESXi server.

Here are a few troubleshooting steps:

1. Network Connectivity: Make sure that the Nagios server can reach the ESXi server over the network. Try pinging the ESXi server from Nagios.

2. Port Accessibility: Confirm that the ports required for communication with the CIM server are open and accessible from the Nagios server.

3. Plugin Configuration: Double-check the configuration of your check_esxi_hardware plugin. Sometimes, a small misconfiguration can cause such issues.

4. Python Environment: Since the script is in Python 2.7, ensure that all the dependencies are correctly installed and that there's no version mismatch that might be causing this problem.

5. Check Logs: Look into the ESXi and Nagios logs for any additional clues that might point to the root cause of this issue.

Hope this helps! Keep us updated on your progress.
