You can configure the security protocols and cipher suites for both components.

For Blast Secure Gateway and the HTML Access agent, by default, TLS 1.1 and TLS 1.2 are enabled and TLS 1.0 is disabled.To support Horizon Client 3.3 and earlier versions, as well as View Agent 6.1.x and earlier versions, if you use the PCoIP Secure Gateway, you can enable TLS 1.0 for PCoIP connections by following the instructions in KB 2130798, Configure security protocols for PCoIP for Horizon 6 version 6.2 and later, and Horizon Client 3.5 and later. View Agent versions earlier than 6.2 also use only TLS 1.0. Horizon Client 3.3 and earlier versions use only TLS 1.0 for PCoIP. For PCoIP connections, by default, TLS 1.1 and TLS 1.2 are enabled and TLS 1.0 is disabled.If the vSphere version is 6.x, it is recommended that TLS 1.0 be disabled for outgoing connections. TLS 1.0 is enabled for outgoing connections to support vSphere 5.x, but is disabled for incoming connections. By default, TLS 1.1 and TLS 1.2 are enabled. To improve security, SSLv3 is no longer supported.For more information, see Resolved Issues. Some known issues from previous releases are resolved.

VMware Horizon View 6.2.1 is a maintenance release.

Release Notes for VMware Horizon 6 version 6.2.1 To provide a bit of background for the issue, let me reference the release notes found at the following URL that describes the TLS changes to PCoIP connections: I finally got a chance to take some time to test the following KB that outlines the steps required to enable TLS 1.0 for backward compatibility with VMware Horizon View 6.2.0 and earlier:Ĭonfigure security protocols for PCoIP for Horizon 6 version 6.2 and later, and Horizon Client 3.5 and later (2130798) Try again, or contact your administrator if this problem persists.” Upgrading from VMware Horizon View 6.0.1 to 6.2.1 causes connections to throw the error: “Unable to connect to desktop: There is no available gateway for the display protocol.
