You might experience connection problems between Horizon Client and a security server or Horizon Connection Server host when the PCoIP Secure Gateway is configured to authenticate external users that communicate over PCoIP.
Problem
Clients that use PCoIP cannot connect to or display Horizon 7 desktops. The initial login to a security server or Connection Server instance succeeds, but the connection fails when the user selects a Horizon 7 desktop. This issue occurs when the PCoIP Secure Gateway is configured on a security server or Connection Server host.
Note: Typically, the PCoIP Secure Gateway is leveraged on a security server. In a network configuration in which external clients connect directly to a Horizon Connection Server host, the PCoIP Secure Gateway can also be configured on Connection Server.
Cause
Problems connecting to the PCoIP Secure Gateway can occur for different reasons.
- Windows Firewall has closed a port that is required for the PCoIP Secure Gateway.
- The PCoIP Secure Gateway is not enabled on the security server or Horizon Connection Server instance.
- The PCoIP External URL setting is configured incorrectly. You must specify this setting as the external IP address that clients can access over the Internet.
- The PCoIP External URL, secure tunnel External URL, Blast External URL, or another address is configured to point to a different security server or Connection Server host. When you configure these addresses on a security server or Connection Server host, all addresses must allow client systems to reach the current host.
- The client is connecting through an external web proxy that has closed a port required for the PCoIP Secure Gateway. For example, a web proxy in a hotel network or public wireless connection might block the required ports.
