How to Fix Autodesk Issue: Requested Service Not Available

Autodesk apps may suddenly stop working or fail to sign you in, showing the message, “Requested Service Not Available” before closing or freezing. This error usually means that the application can’t reach important Autodesk services needed to check your license, confirm your user account, or sync your projects.

The most common reason for this error is a broken or outdated Autodesk Identity component. This can often happen after software updates, reinstalling the program, or making changes to your system. Other possible causes include a damaged login cache, incorrect Single Sign-On (SSO) setup, or missing TLS security files on Windows.

In this guide, we’ll walk you through different methods to fix the “Autodesk Requested Service Not Available” error.

1. Change the Time Zone

This error can often occur when your computer’s time zone doesn’t match the current local time. It’s important to check and adjust your system clock and time zone according to your region.

1. Open Windows Settings by pressing Win + I together.
2. Go to Time and Language > Date and Time.
3. Set the time zone to match your actual location by turning on “Set time automatically” and “Set time zone automatically”.

   

4. Once your time and time zone are correct, try logging in to Autodesk again.

2. Turn Off Your VPN Connection

Autodesk programs usually don’t work well with a VPN connection. Because VPNs act as third-party networks, they can interfere and cause login errors

1. Open Windows Settings with Win + I.
2. Go to Network and Internet > VPN.
3. Click the connected VPN and select Advanced options.
4. In the Manual Configuration section, turn off “Use a proxy server”.

   

3. Create a New Windows User Profile

A corrupted Windows user profile can prevent you from logging in to Autodesk, causing this error. If you suspect your profile might be corrupted, you should create a new Windows user profile. Before creating a new one, back up your important data to avoid losing it.

4. Update Your Windows

An outdated version of Windows can sometimes interfere with Autodesk products, leading to login or connectivity issues. Make sure your Windows is fully updated.

1. Open Windows Settings by pressing Win + I.

4. When finished, restart your computer by clicking Restart Now.

   

5. Try running Autodesk and logging in again.

5. Disable Windows Protection

Windows protections like Windows Defender or Firewall can sometimes block Autodesk software from running correctly. To see if they are causing your issue, try temporarily disabling them.

1. Open Windows Settings using Win + I.
2. Navigate to Update and Security > Windows Security > Firewall & Network Protection.
3. Turn off all active firewalls by selecting the network types (Domain, Private, or Public) and switching off the firewall.

   

4. Disable Windows Defender Firewall by toggling the “Windows Defender Firewall” switch to Off.

   

5. Confirm any prompts by clicking YES if asked by User Account Control.
