Over the past week, a number of readers have reported SSL 4 Citrix Access Gateway vpx bug.
We’ll cover design elements such as a certificate chain tied to a virtual server, cipher suite configuration options, and disabling old, vulnerable and vulnerable protocols. There are many tools with which it can be used to validate the layout of a Citrix ADC protected public site. One such tool is usually the Qualys SSL Labs SSL Server Test.The StoreFront / VDA connection fails and the TV show may not connect to the server. Error or some SSL certificate errors in console logs. One of the reasons could be an invalid SSL certificate. Citrix Receiver for HTML5, Citrix Receiver for Chrome, Citrix Workspace App for Chrome, Citrix Workspace App for HTML5 Recommended software: Renew certificates.
We have a reliable laboratory that is not on our Internet. Has its own internet connection
And from all points of view, the connection is almost indistinguishable from the connection with many other companies
which uses AG and ICA Proxy
First, everything works, externally and internally 110%
For example, this is a very general simple connection
Internet -> 443 -> Firewall -> 443 -> AG_VIP -> NetScaler VPX -> SNIP -> Citrix Farm
So what’s the overview, our corporate network uses Websense
And it blocks everything except ports 80 and 443
Which shouldn’t be a problem with the ICA proxy as you need all 443 and a new certificate
We had to add our website url to the allowed list, which has now been added
When we try to login, we can login and our apps usually show up in the
listBut when we start practically with them, we get messagesNot about the “Impossible” error
> to launch your application. Contact support to provide fanbase information:
> The Citrix XenApp server could not be connected. SSL Error 4:
> Access to the proxy server is denied; ten; STA4DC346E4BD76; CF94ACEA4D3137CC11495FEFFB4DBD92 port 1494.
I know that the laboratory is fine, because it works everywhere except work
And at first glance, it is worrying that access to open 1494 is denied because we are using ICA proxies
and why does Websense think I want to connect to port 1494
Can I ask the Websense administrator to do something to make this work?

It seems to me that I am currently configuring a NetScaler gateway 12.1 (48.13) with a Windows 1709 10 VDI environment using XD 7.15 with the latest CU. For some reason, I am unable to properly configure NSG for this environment. The problem I am facing is definitely when I try to run a widely published desktop; I got the error: ssl “SSL error 4: operation completed successfully”.
There are many posts on the internet describing this problem. There are solutions with an upgradem NetScaler (but I have already connected a later version), the problem also increases with Windows 10, but 1703; I am running 1709. I also tried to change the order of the ciphers in the VDI without a doubt; the fact that that didn’t solve it either. Down and updated the same recipient; Go out. I do not check for any non-certification issues; Meet something strange with SSLLabs. But of course I am missing something, otherwise it would take a lot of effort 🙂 Basically I run out of ideas, usually associated with ideas; Anyone have an idea?
Could you make sure that the following guidelines are listed in the weight loss article in the relevant VDAs?
Basically add the following line to the SSL Cipher Suite GPO VDA folder:
If not, can this be done on the VDA wall and in general behavior?

Solution
- Check the listener version used by the respective clients and make sure it is TLS 1.1 and TLS 1.2 compliant:
- Receivers below 4.2 are only compatible with SSL from v3 and TLS 1.0.
- Correct receiver version 4.2 (including 4.2) is compatible with SSL v3 and 1 tls.0, TLS 1.1 and TLS 1.2.
Cause Of The Problem
- Receiver 4.1 only supports SSL and TLS v3 v1.0.
- Receiver 4.4 installed
