• If you disable triple DES on the VDA with SSL enabled.
• The Application Launch and Desktop Launch will fail with SSL error.

• Run the below command to configure the SSL Cipher Suite on the VDA to ensure the ICA connection to VDA does not use Triple DES
• Enable-VdaSSL.ps1 – Enable –SSLPort 443 –SSLMinVersion “TLS_1.2” –SSLCipherSuite “COM”

Problem Cause
