# Failure to Schedule Inventory Scanning

Last Updated On: 18 Sep 2026

## Problem

You have scheduled Inventory Scanning, but it failed.

## Cause

Scheduled Inventory Scanning may fail if the Firewall on machine running Endpoint Central Server blocks data.

## Resolution

**Unblock Firewall Port:** Check if the Endpoint Central Port (default is 8020) is added to the exceptions list. Follow the steps to add the ports to the exception list:

1. Go to *Start* and select *Control Panel*.
2. Choose Windows Firewall.
3. Select the *Exceptions tab*
4. Click on *Add Port* button and add the ports as 8020 or your server http port and 8383 or your secure https port respectively.
