Connectivity issues can occur when using the Video Management System (VMS) behind a firewall. This is because the VMS generates internet traffic when they are connected to the internet. 

To make sure you can connect to the Cloud services, you need to add a list of endpoints to your firewall's passlist. Check out the support article 'What Internet Traffic Will Nx Witness System Generate?' to learn more about the internet traffic that is generated by Nx products. 

Firewall Passlist

When configuring up your firewall, make sure to use a specific naming system called FQDN. 

This is important because it allows you to add specific services to your passlist. Some services don't have a fixed IP address, so using FQDN ensures that you can add them to your firewall's passlist.

List of FQDNs

Please note, that you add all the FQDNs listed in the script output or the CSV file at the bottom of this article to your firewall passlist. It's important to include all of them, not just those specific to your region, for seamless functionality.

To learn more about the different cloud components, there's a support article you can check out for more information.

To obtain a full list of FQDN addresses, along with their current IP addresses (optional), you can find a Python script available on the Network Optix GitHub repository. This script also allows you to check the accessibility of these addresses. Additionally, for convenience, if your firewall application supports CSV file uploads, the script provides an option to download the addresses in CSV format.

When running the script, if some or all addresses are reported as closed, check the Maintenance and Incidents feed for any known issues. If no issues are reported, ensure the endpoints are added to the firewall passlist and/or create an exception in the antivirus software as needed.

Mobile use

Python can be used on Android or iOS as well, and you can download an app to run a Python script on your preferred platform. 

For example: 

For Android: Pydroid3
For iOS: Pythonista

Beta Script in EXE format

Below, you'll find the CloudServiceChecker script in EXE format, converted from the Python script to EXE specifically for Windows systems where Python may not be installed.

Please keep in mind that the EXE version has limited maintenance and may not always reflect the latest updates. For the most up-to-date version, we highly recommend using the native Python script available on our GitHub account. You'll also find a detailed README file there with clear instructions to help you get started.
