Products and versions covered

Issue:

Users have reported having problems connecting to the Autodesk servers when trying to use or install Autodesk Fusion.

Potential indicators for network connectivity problems include:

  • Error 407 during download or installation (may indicate a conflict with your office proxy server settings). 
  • The sign in window is not displayed when starting Fusion for the first time. 
  • Sign in Errors (Authentication Errors). 
  • Error message "Unable to set up Fusion for your Autodesk account" appears during startup. 
  • The Fusion dialog boxes are solid gray only. 

Causes:

Fusion is a cloud based software that requires access to the internet. Some network configurations or user environments may prevent Fusion from connecting to the internet and contacting Autodesk web services.

Solution:

For issues updating or installing Fusion, try this troubleshooter form to help solve the most common issues or visit "Problem installing Autodesk Fusion" when installing Fusion. 

Run a Network Diagnostic Test with the Fusion Service Utility: 

Fusion Service utility Menu

Verify the Network Configuration: 

Confirm that the network is configured to have open access to the ports and domains required for Autodesk Fusion. See Ports and Domains required by Fusion. 

 

Configure Network Preferences in Fusion:

If you suspect your proxy server may be causing a conflict with Fusion, add the proxy server's information to the network settings in Fusion.

 

Configure your proxy server and firewall for Fusion:

If you suspect the proxy server may be causing a conflict, see the following links for how to configure your firewall or proxy server settings for Fusion.

 

Configure 3rd party security software (anti-virus or firewall software):

Some anti-virus and firewall programs may prevent normal operation of Fusion. See Configuring anti-virus software for use with Fusion. 

 

Remove interferences from software programs running in the background:

Applications running in the background may prevent Fusion from running normally. Use the procedure in the following link to help diagnose these interferences. See Diagnose Interference from background processes in Windows using Safe Mode for help diagnosing and configuring anti-virus software or firewalls to work with Fusion.

 

Reference the log files to learn more about the nature of the issue:

Many network activities in Fusion are recorded in one of 3 log files. See: How to manually collect the log files for Autodesk Fusion (How to manually gather these log files and how to analyze them.) 

 

Check Time, Date, Timezone, & Daylight Savings Time (DST) Settings:

Accurate time and date settings are important to connect with Autodesk services. See Time mismatch with Server warning when starting an Autodesk application.
