How do I fix VMware Horizon Client disconnection?

The Horizon Client is a software application developed by VMware that allows users to connect to virtual desktops, applications, and remote desktop services. It is commonly used in virtualized environments where users need access to virtual machines or desktops hosted on servers. The error message "The Connection to the Remote Computer Ended" on Horizon Client indicates that the connection between your local device and the remote computer has been terminated.

3 steps to fix "The Connection to the Remote Computer Ended" on Horizon Client

If you happen to encounter this problem, don't worry. In this section, we'll guide you on how to address the issue of "The Connection to the Remote Computer Ended" on VMware Horizon Client in three steps.

Step 1. Enable PCoIP Gateway functionality on the Connection Server

Navigate to the Configuration Servers in View Administrator. Select a Connection Server, then click Edit and check the box that says "Use PCoIP Secure Gateway for PCoIP connections to desktop". PCoIP will then gateway through either the associated Security Servers or this Connection Server for all users of this Connection Server and any Security Servers.

Step 2. Set up the “External URL” and the new “PCoIP External URL” on the Security Server

View Clients use these URLs to connect to a certain View server. Clients must be able to resolve and use these names and addresses. If distant connections are made directly to the Connection Server, External URLs must be configured on the Connection Server as well.

Step 3. Update the firewall to allow PCoIP to pass through

The final part is to check if a UDP port is blocked. You’ll need to install netcat for Windows on the View Client, the View Security Server, and the View desktop virtual machine.

• To test UDP connectivity from the View desktop to the Security Server:

Step 1. On the Security Server, open Command Prompt, run the command “nc -l -u -p 4172” to set the Security Server to listen on port 4172 for UDP traffic.

Step 2. On the View desktop, open Command Prompt, and run the command “nc -u Security_Server_IPaddress 4172” to transmit traffic over UDP port 4172 to the destination IP address.

• To test UDP connectivity from the Security Server to the View Desktop virtual machine:

Step 1. On the View desktop virtual machine, open Command Prompt, and run the command “nc -l -u -p 4172” to set the View Desktop to listen on port 4172 for UDP traffic.

Step 2. On the Security Server, open Command Prompt, and run the command “nc -u View_Desktop_IPaddress 4172” to transmit traffic over UDP port 4172 to the destination IP address.

• To test UDP connectivity from the Security Server to the View Client:

Step 1. On the View Client, open Command Prompt, and run the command “nc -l -u -p 4172” to set the View Client to listen on port 4172.

Step 2. On the Security Server, open Command Prompt, and run the command “nc -u firewall_IPaddress_in_client_environment 4172” to transmit traffic over UDP port 4172 to the destination IP address.
