Marvelous Designer Support

Use this guide to understand TLS 1.2 compatibility and check connection problems when starting or signing in to Marvelous Designer.

What is TLS 1.2?

TLS 1.2 is a version of Transport Layer Security (TLS), a protocol that encrypts data sent between an application and a server.

Can TLS compatibility affect startup or sign-in?

TLS compatibility can affect the secure connections used during startup or sign-in. The operating system, application, and network configuration all play a part.

What should I check?

1. Check the Marvelous Designer System Requirements to confirm that your operating system and hardware meet the requirements for the version you use.
2. Install applicable operating system updates. See the Windows update guide or macOS update guide. Before upgrading to a new major OS version, check that it meets the Marvelous Designer system requirements. Restart if requested, then try starting or signing in again.

How can I get help?

If the issue continues or you encounter any of the following symptoms, submit a request through Contact Us.

• The error message "Delayed Network Connection" appears when you try to sign in.
• The sign-in window does not appear.
• The software does not respond after a sign-in attempt.

These symptoms can have causes other than TLS and do not by themselves confirm a TLS problem.

Include your Marvelous Designer version, operating system version, a screenshot of the complete error message or affected screen, and a description of when the problem occurs.

Browser or website TLS errors

For a TLS error that is limited to your browser or another website, consult the help provided by that browser or website. For Marvelous Designer startup or sign-in issues, use Contact Us above.
