Overview

This article discusses error messages that may occur while launching TLS or DTLS encrypted sessions when using the Citrix Receiver for Windows 4.12 and describes the possible causes of each error message. It also provides troubleshooting steps for each issue. In addition, this article is intended for system administrators.

Update

If these troubleshooting steps do not resolve your issue, please use a network tracing tool such as Wireshark to capture TLS and DTLS network traffic. TLS and DTLS network traffic should be captured at the client device, Citrix NetScaler Gateway, and VDA (if possible). Please be ready to supply this information to your Citrix support representative when requested.

Resolution 2

If you receive a “Socket Operation on Non-socket” error message while attempting to connect to an Application or Desktop using Citrix Receiver for Windows 4.12, this is because the configuration on the client and/or VDA is currently un-supported. For a supported matrix configuration, go to Receiver for Windows Crypto Kit Updates article.

Used case

For instance, if the setup has FIPS compliance mode enabled and the COM cipher set has been configured on the Client and VDA, session launch fails with Citrix Receiver for Windows 4.12 due to lack of common cipher suite. You can change the configuration to GOV or ANY on client and VDA to resolve the same.

Resolution 3

New Citrix Receiver

If you receive “SSLv3 alert handshake failure” error message, this is because certain deprecated RSA cipher suites have been explicitly disabled in Receiver. Some configurations still require these deprecated cipher suites. You can re-enable these cipher suites using the Receiver Group Policy template as follows.
