AggFlow DM Product Information
Created by BedRock Software. Inc., AggFlow DM is a software program that is used to model and optimize aggregate plant simulations. AggFlow DM is a dynamic program that requires regular program/database updates, license verification, and user registration. As such, it is critical for the AggFlow program to communicate with the AggFlow DM server regularly.
To Resolve AggFlow DM Connectivity Issues
AggFlow DM requires connectivity to these ports for all communications and downloads:
- For updates HTTP access to:
*.aggflow.com, port: 80. - For communication & downloads HTTPS access to:
*.aggflow.com, port: 443.
Alternative Option
Simply grant AggFlow DM server access by adding this web address to the company’s AUTHORIZED list: *.aggflow.com
This will allow direct connection without filtering. In this case the proxy server settings are not required and should be removed (unchecked) from the Internet Settings Window.
