Transport Layer Security Changes

As of July 28, 2020, support was discontinued for devices that utilize SSL/TLS 1.1 and earlier protocol versions. TLS versions 1.0 and 1.1 are out-of-date Transport Layer Security protocols that do not support modern cryptographic algorithms.

Most encrypted Internet traffic is now sent with TLS 1.2 & 1.3 for the increased security against vulnerabilities that may be exploited by attackers with older protocols. As so, older machines may need to have TLS 1.1 disabled in the DW Spectrum Server program.

This article will outline how to disable TLS 1.1 on a DW Spectrum Server machine using Windows or Ubuntu Linux.

 

**NOTE:  Disabling SSL/TLS 1.1 will cause an inability to connect with DW Cloud if your system has ARM-based devices running DW Spectrum v3.1 or older, including:

• Raspberry Pi
• DW Edge (CaaS Series)
• Any other compatible ARM-based device

 

Disabling TLS 1.1 on a Server

3. To edit the string, double-click on allowedSslVersions and enter “TLSv1.2” into the Value data box.

 

4. Click the OK button to close the Edit String window.

Close the Registry Editor and restart the DW Spectrum Media Server service or reboot the machine.

 

Using Ubuntu Linux

To disable TLS 1.1 on a Linux machine:

1. Navigate to:

 

2. Open the mediaserver.conf configuration file.
