TdUdtListenerCreate: Retry number XX to listen: Listener <Hex number>  on port 2598",""
"setListener failed",""
CUDTUnited::listen failed. Error:-28",""
CUDT::listen Error:-28",""
TdUdtListenerCreate: UDT::listen error 0xffffffe4",""
 

Resolution

Workaround:
Disable EDT - Turn Off HDX Adaptive Transport from Citrix Policies:

 

Problem Cause

The failure to create a UDT listener indicates that Enlightended Data Transport (EDT) is in use and that there is a problem with the UDP sockets.
