XenApp 6 Fundamentals not working with iPhone/iPad

Hi Team,

We have just single server installation of XenApp Fundamentals 6 with Rollup 2 update etc on W2K8 R2 server.

We were able to access XenApp via Citrix receiver before 5.8 update and now I've also tried 5.8.1 but it still hangs at "Starting Application" phase with error "Could not connect to server".

Our Windows, Mac and android access are fine, its just iOS access for both iPhone and iPad with latest iOS version. During application launch it authenticates fine but fails at next stage of starting app. Please refer to screenshots.

On the server we get below errors for iOS devices:

Error: "SSL Library error 45 on citrix.XXXX.co.uk:443 with client operation completed successfully.
    Source: Citrix Secure Gateway
    Event ID: 127

Warning: "SSL Handshake from client failed".
     Source: Citrix Secure Gateway
     Event ID: 125

Please look into it for us.

To me it looks like my server uses TLS 1.0 and for iOS I require TLS 1.2 support but don't know how can I add it to my existing setup.

Is it done on the Windows 2008 R2 side without touching anything on Citrix end like using setups below:
