When the window freezes, first, try resetting the remote desktop operating system.
Horizon Client does not work or repeatedly exits unexpectedly or the remote desktop freezes.
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.
- 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.
- Uninstall and reinstall the app on the device.
- 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.
- 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.
