Description

When the connection comes via NetScaler intermittently users get grey screen while launching Desktop and then connection gets closed with error: 'Connection interrupted'.

The issue is not seen when we by-pass NetScaler / attempt connection internally.

Resolution

Disabling AppFlow feature on NetScaler 12.0.41 fixes the issue.

Upgrading NetScaler to 12.0.53.22 addressed the issue with AppFlow feature enabled.

Problem Cause

NetScaler intermittently modifies the packet due to which VDA closes the connection.
CDF shows error: 'WdDropSession - Dropping session to save server'
