Horizon Client Stops Responding or the Remote Desktop
Freezes
When the window freezes, first, try resetting the remote desktop operating system.
Problem
Horizon Client does not work or repeatedly exits unexpectedly or the remote desktop freezes.
Cause
Assuming that Horizon servers are configured properly and that firewalls surrounding them have the
correct ports open, other issues usually relate to Horizon Client on the device or to the guest operating
system on the remote desktop.
Solution
n
If the operating system in the remote desktop freezes, use Horizon Client on the device to reset the
desktop.
This option is available only if the Horizon administrator has enabled this feature.
n
Uninstall and reinstall the app on the device.
n
If resetting the remote desktop and reinstalling Horizon Client do not help, you can reset the iOS
device, as described in the device user guide from Apple.
n
If you get a connection error when you attempt to connect to the server, you might need to change
your proxy settings.
What to do next
If the problem is with the operating system inside the remote desktop, see Reset a Remote Desktop or
Remote Applications.
Problem Establishing a Connection When Using a Proxy
Sometimes if you attempt to connect to Connection Server using a proxy while on the LAN, an error
occurs.
Problem
If the Horizon environment is set up to use a secure connection from the remote desktop to Connection
Server, and if the client device is configured to use an HTTP proxy, you might not be able to 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 Connection Server using an internal address, you might see the error message Could not
establish connection.
