Network traffic is blocked at Port 475 on the computer where the license key is installed and/or protected software is running (due to Windows Firewall or, for example, antivirus software).
Disable all software that may block access to your license key or add a blocked object into a list of exceptions (whether it is Port 475, Sentinel LDK Run-time or other software blocked).

“Terminal services detected, cannot run without a dongle (H0027)” error
Cause
Solution
Occurs when terminal services are detected. For example, Microsoft Terminal Server (including Remote Desktop services), Citrix Winframe/Metaframe etc.
Your license key should not be connected to a computer that has active terminal software installed. VIT controls this option by allowing or prohibiting operation on terminal servers: if such option is needed, request for the license key update:
54 UpdateTooOld Trying to install a V2C file with an update counter that is out of sequence with update counter in the Sentinel protection key. Values of update counter in file are lower than those in Sentinel protection key.
55 UpdateTooNew Trying to install a V2C file with an update counter that is out of sequence with the update counter in the Sentinel protection key. First value in file is more-than-1 greater than value in Sentinel protection key.
