Is your View environment set to connect using TLS 1.0? VMWare horizon view 4.10 was released a couple weeks ago and removed support for TLS 1.0.
I copied this over from a different thread.
What version of the Horizon Client are your endpoints using? 4.10.0 was released earlier this month which disabled support for TLS 1.0. You need to be on Horizon 6.2.1 or newer where TLS 1.0 is also disabled for the newer clients to work.
You should start prioritizing an upgrade or migration to Horizon 7.x as Horizon View 6.x goes end of general support in just over 6 months on 2019/06/19.
There is a VMware supplied workaround available.
There is a per-device workaround that allows Horizon Client for iOS 4.10 to continue working with TLS 1.0:
- Create a new file named config.txt
- Add a new line to this file:
- Connect the iOS device to a computer that has iTunes installed
- Open iTunes and select File Sharing on connected device
- Select Horizon in Apps
- Click Add… button to add config.txt into Horizon App
- Relaunch Horizon App
The latest Horizon Clients have turned off support for TLS 1.0, an older encryption framework with multiple security vulnerabilities. If your company is on an older version of the server software, for instance Horizon View 5.X, it won’t support the newer encryption connections. There is a work-around for mobile clients that I have been sharing with companies when they reach out to me. Otherwise, you can stay on the Horizon Clients 4.9 until you can update your environment.
