Ports and Domains required by Fusion

2025-08-05

Technical Support

Issue:

Users reported that access to the online services for Autodesk® Fusion™ is required:

A proxy server, firewall, or anti-virus software may be interfering with the normal operation.
Looking for a list of domains and ports that Fusion uses during normal operation to help configure the network.

Causes:

The data panel uses an embedded web browser component based on Google Chrome, which always uses the default system proxy configuration settings. The Fusion login process also uses the default system proxy configuration. Other parts of the software, specifically our interactions with the data management service and the file upload system rely on the settings in the Fusion Preferences.

Solution:

Required Ports

Required Domains

Unrestricted access to the following domains (the following domains have anonymous access through the proxy server for installation)

*.autodesk.com
*.autodesk360.com
*.appstreaming.autodesk.com
*.api.autodesk.com
*.cloudfront.net

Fusion may contact the following servers during normal operations:

accounts.autodesk.com
appstreaming.autodesk.com
fusionapi.autodesk.com
notifications.api.autodesk.com
ui-dls360.autodesk.com
signin.autodesk.com
idp.auth.autodesk.com
autodesk360.com
amazonaws.com
akamai.com
akamaitechnologies.com
tracepartsonline.net
mcmaster.com
*.s3.amazonaws.com
*.s3-accelerate.amazonaws.com
*.launchdarkly.com
damassets.net
*.library.io
pubnub.com
pndsn.com
requirejs.org
google-analytics.com
googletagmanager.com
api.hcaptcha.com

Note: Proxy applications may require special notation (for example, *.*.autodesk.com) to enable wildcards for the domains. Some domains have dynamic IP addresses, any exceptions added to firewalls or proxy servers must configured by domain name and not the IP address.

Configuring Firewall or Proxy servers

Work with network administrator to determine the proper procedure to configure the network for access to these ports and domains. To configure your firewall or proxy server for Fusion, see the below solution articles:

Note: There are known limitation if the proxy server needs to be authenticated against and it uses the ‘Negotiate’, ‘NTLM’, or ‘Kerberos’ authentication method. The only workaround is to add that list of hosts to the exception list of the proxy server.

Fusion Network Diagnostic

To check the current status of any ports and domains used in Fusion, run the network diagnostic test command in the Service Utility. See: Overview of Network Diagnostic Test Command from Fusion Service Utility
