HTML5 connections to Virtual Aps:

Bril licenses


HTML5 client error in session log:

 SESSION:|:ICA:|:TRANSPORT:|:DRIVER:|:error with code=18 , name=SecurityError , message=The operation is insecure


As per the Citrix Support article it says for this issues one of the 2 below solutions should work. I cannot use solution 1 now.

so I configured the connections to go through NetScaler ADC. the issue persists.

if i am using Workspace client all connections are OK.


I even tried enabling the firewall setting to all not secure communication over html.


Solution 1 is to enable SSL on the VDA using the following guide:

This will ensure that the connection path is SSL enabled between the internal client and the VDA.
Solution 2 is to have your connections from the clients first go through a Citrix Gateway. Citrix Gateway will proxy the connections and perform a SSL handshake between the client and the Citrix Gateway.  In this scenario there is no inconsistency and connections via HTML5 Receiver will succeed.

thanks Jeff for the response.


attached is my http profile. I have tried including the all websockets option but the issue persists. and ofcourse I am using this with ICP proxy.

Although I am not quite use my ICA proxy setting is effective. because I realize even if I am using the Workspace app and not the html the established sessions are directly from the client IP to VDA. so how exactly is my ADC doing a proxy for ICA connection? i dont know
