When you attempt to connect to a server by using a proxy while on the LAN, an error sometimes occurs.

Problem

If your Horizon environment is set up to use a secure connection from a remote desktop to a server, and if the client device is configured to use an HTTP proxy, you might not connect.

Cause

Unlike Windows Internet Explorer, the client device does not have an Internet option to bypass the proxy for local addresses. When an HTTP proxy is used for browsing external addresses, and you try to connect to a server by using an internal address, you might see the error message Could not establish connection.

Solution

  1. Remove the proxy settings so that the client device no longer uses a proxy.
