Server Connection issues with the License Manager Tool (LMT) and websites

Updated

Issue description

You are likely reading this because a "This Connection Is Not Private", "Security Risk" or even a "404 Page Not Found" error is preventing you from signing into the License Manager Tool (LMT) or accessing Graphisoft web services. This happens because your Internet Service Provider (ISP) or a local firewall is "inspecting" and altering security certificates, which breaks the background browser Archicad uses for authentication. This article will help you identify the source of this blockage and restore your connection.

 

Solution

Follow the steps below in order, testing the connection after each individual step.

 

Pre-Troubleshoot Connection Test

Before proceeding with the troubleshooting steps, perform this quick test to confirm if your network or ISP is interfering with the connection:

  1. Open your default web browser on the affected computer.

  2. Manually navigate to: https://id.graphisoft.com .

  3. Analyze the result: If you receive a warning such as

    • "This Connection Is Not Private"

    • "Security Risk"

    • "Can't Connect to Server" or

    • "404 Page Not Found"
      your network is actively breaking the encrypted connection.

  4. Follow the steps below to troubleshoot the issue.

Web browser cache issue

The issue may be caused by cached data in your browser. Try using an incognito/private window to disable cookies, extensions, and cache.

  • Incognito mode in Google Chrome
  • Private window in Mozilla Firefox
  • InPrivate browsing in Microsoft Edge
  • Private browsing in Safari

If the service works correctly in private mode, clear the cache in your browser:

Check Antivirus/Security Apps

If you use Norton, Bitdefender, Little Snitch, etc., open their settings and add *.graphisoft.com to the "Web Shield" or "Exclusions" allow list. For additional sites that may be whitelisted, see the hosts list on the next section.

Whitelist our web domains

If you manage your own router/modem, look for settings labeled "Web Filter," "SecurityEdge," "Phishing Protection," or "Homeshield".

If your Internet is managed by an external Internet Service Provider (ISP) or IT department, please forward the list below to them and request that they whitelist these domains to bypass the inspection.

Disable third-party application blocking the connection

You may have a third-party application blocking the connection. By disabling or uninstalling such a third-party network monitoring utility, the issue may resolved.

  1. Close all apps and open only Archicad.
  2. Check the Menu Bar (macOS) or System Tray (Windows) for uncommon background apps (e.g., Little Snitch, widgets, audio enhancers).
  3. Temporarily disable or remove these apps to see if they cause issues.

Disable third-party browser plug-ins/extensions

Some browser plug-ins can interfere with the sign-in process. To test:

  1. Open your web browser.
  2. Disable any third-party plug-ins, add-ons, or extensions.
  3. Launch the License Manager Tool or attempt to use our Websites again.

Test with a new user account

This is a final test to help determine the nature of the problem, whether it's related to something local like user profile settings or network issues. Some problems might be linked to specific user accounts. 

Try creating a new administrator-level user account to test:

If the issue is resolved in the new account, this indicates a problem specific to your current OS profile (permissions, security, or configuration). If the issue persists, you can delete the test account.
