Cloud Connection Requirements

Cloud functionality in InfoWorks ICM uses the Info360 Cloud Model Service for database hosting, simulation execution and results storage, which requires the InfoWorks ICM client machine to be connected to the internet. Connections to these services are done over HTTPS, via port 443 using TCP. Depending on the data hosting region that your hub is located in, the following domains need to be added to an allowed list on the InfoWorks ICM client machine:

If your system does not allow adding wildcards, see the specific domains in the "Login, License Entitlement" section below.

Note: URLs that are italicized are example domains under * for the third party certificate download and verification sites.

Proxy server

If a proxy server is used for internet access, InfoWorks ICM will automatically detect the proxy server settings. If a username and password is required, a dialog is displayed by Autodesk licensing. The username and password are stored in the Windows Credential storage.
Important: By default, automatic proxy server detection only applies to Autodesk licencing and not to Info360 cloud database connection. By default, no automatic detection is attempted for cloud database connections.

Automatic detection of the proxy server for cloud database connections can be controlled by adding a Windows system environment variable with the name INFOWORKSINFO360PROXY.

Note: This must be set as a system environment variable not a user environment variable otherwise cloud simulations will fail because the agent runs as local system.
The variable value can be set as follows:
  • AUTO - Automatic detection is attempted. The proxy server settings from the Autodesk Identity Service are used.
  • Anything else - where Anything else is a string to be used as the proxy setting. This would normally have the form "ip-address:port" or "http://ip-address:port". Note that a port must be specified. See CURLOPT_PROXY for further information.
  • NONE (or not set) - No proxy server is used. A "Failed to connect to server" message is displayed when a user tries to access a cloud database in ICM.

Notifications

If the INFOWORKSINFO360PROXY environment variable is defined, you must also configure your firewall to allow connection to the notification service on port 443 in order to detect when simulations have completed or database items have changed in other ways.

Proxy configuration for Info360 cloud database connections

The following table provides information on the supported proxy configuration for Info360 cloud database connections in InfoWorks ICM (from version 2025.2):

Note:
  • Only the basic proxy authentication scheme is supported from InfoWorks ICM version 2025.2
  • Credential Manager in Windows should be enabled.
