This will be via the Blast Secure Gateway on the same Unified Access Gateway appliance as the one where the user authenticated. The initial authentication phase of a connection is from the Horizon Client to a Unified Access Gateway appliance and then to a Connection Server. Whilst the information provided is correct to the best of my knowledge, I am not reponsible for any issues that may arise using this information, and you do so at your own risk. This prompt can appear the first time you connect to a server on which shortcuts have been configured for published applications or remote desktops.

The connection to the remote computer ended on log off (2146139 We are currently struggling to get a VMware View security server working behind a FortiGate firewall (version 4.0 MR3) as well. The Horizon Connection Server securely brokers and connects users to the Horizon Agent that has been installed in the desktops and RDS Hosts. To troubleshoot a Horizon connection, first determine which phase is failing (authentication or protocol). For more information about VMware Horizon Client connections, you can explore the following resources: The following updates were made to this guide: Added info on how to check certificates used by Unified Access Gateway. The following diagram shows the ports required to allow an external RDP connection through Unified Access Gateway. The toughjob was going through each setting and testing it to find which (initial guess work was not sucessful). Nehmen Sie an der Unterhaltung teil und lernen Sie auf unserer Community-Website von anderen. You can look at logs to see connection failures on these ports. Provided all these steps have been followed the security server should be working as expected. This setting is available only if the Log in as current user feature is installed on the client system. The Horizon View infrastructure brings flexibility, efficiency, and customer ease of use. Monitoring the Last Mile of a Horizon Session Using Remote DX Ensure that any firewall present allows this traffic from the Unified Access Gateway to the Agent and that network routing is in place to allow and direct the traffic. Download VMware Horizon Clients Select Version: Horizon 8 VMware Horizon Clients for Windows, Mac, iOS, Linux, Chrome and Android allow you to connect to your VMware Horizon virtual desktop from your device of choice giving you on-the-go access from any location. To see more detail on the network ports required for an external connection, see Network Ports in VMware Horizon: Internal Connection and the Internal Connection diagram. I recommend posting your question on VMware forums. If the Blast connection is misrouted to the wrong Unified Access Gateway appliance and that appliance has a different certificate to the correct appliance, this also causes connection failures. Redirection setup option is deselected by default. Figure 1: Primary and Secondary Protocols. Unified Access Gateway to Third-Party Identity Provider, Unified Access Gateway to Connection Server, RSA Authentication Manager Hostname Resolution, Horizon Client logs into a Connection Server, Horizon Client connects to the Horizon Agent running in the desktop/ RDSH, The user uses the Horizon Client to log into a Connection server via a Unified Access Gateway. Figure 13: External Connection Full Communication Flow. The default limit of 2,000 can be adjusted on request. The load balancer affinity must ensure that XML-API connections made for the whole duration of a session (default maximum 10 hours) continue to be routed to the same Unified Access Gateway appliance. I will be calling VMware support tomorrow to fix the issue.

When the upgrade is complete, the VM will be rebooted automatically. Knowing what is meant to happen during a successful connection helps you understand and troubleshoot when things do not work. The Connection Server authenticates users through Active Directory and directs the request to the appropriate and entitled resource.

The following diagram shows the ports required to allow an internal PCoIP connection. Troubleshooting connectivity issues between the agent, client - VMware A feature on the Horizon Connection Server helps overcome these constraints. Microsoft RDP : The connection to the remote computer failed. UDP 80 from Client to Security Server (If not using SSL, not recommended) This can be done at any point in time after installing the 22.1.0/9.2.0 Horizon Air Link appliance, including after upgrading the platform Management appliances (SPs and RMs). 08-12-2020 10:59 AM The connection to the remote computer ended. Data Sorting in Exported User Activity Report - When you export data from the Users tab of the Activity page (Monitor > Activity > Users), the data in the generated .csv file is not sorted by date. This removes the need to change the default way that the Connection Server sends the machine or RDSH server information to the host. Figure 9: Blast Extreme Network Ports for External Connections. Before upgrading to Horizon DaaS 9.2.0, confirm thatthe service provider and tenant appliances in your environment are running Horizon DaaS 9.0.0, 9.0.1, 9.0.2, 9.1.0, 9.1.1, 9.1.2, 9.1.3, or 9.1.4. Make backups and record various configuration and system settings In the master VM, try to redeploy the virtual machine with the following registry settings, Registry Location:HKCU\Control Panel\Desktop, Windows Activation/AppStack Attach fails when connecting from Horizon, Horizon Connection server cant connect to vcenter - Certificate Validation Failed, iOS - Horizon server connection failed http error 400. To connect to the same remote desktop each time you log in, select Autoconnect to This Desktop from the Options menu on the menu bar in the remote desktop window. The blastExternalUrl is a configuration on the Unified Access Gateway that specifies the URL and port that should be used by the Horizon Clients to connect with Blast to the Unified Access Gateway. The secondary protocol session then normally connects directly from the Horizon Client to the Horizon Agent. You can also look at the DNS protocol activity (requests and responses) by using tcpdump on the Unified Access Gateway. When correctly configured, UDP datagrams will be seen sent on destination port 5500 and reply datagrams from that port will also be seen. VMware Horizon Client 4.5 for Windows : User manual : Page 12 Keep in mind the recommended maximum of 12 tenants supported per Tenant RM.

The initial troubleshooting steps should involve: The main areas of the communication flow that should be investigated are: On the primary authentication phase, the Horizon Client connects to one of the Unified Access Gateways. UDP 4172 from virtual desktop to Security Server 5. This can help determine the best architecture, understand the traffic flow, and network ports, and help in troubleshooting. Because the secondary protocol connections go directly from the Horizon Client to the Horizon Agent, they do not need to be load balanced. It allows creating and brokering connections to Windows & Linux virtual desktops, Remote Desktop Services (RDS) applications, and desktops. Note that it is still supported to have a load balancer in between them but for new deployments the preference is to have a direct mapping of Unified Access Gateway to Connections Server. Where the load balancer does not have this capability, or where source IP affinity cannot be used, another option is to dedicate additional IP addresses for each Unified Access Gateway appliance so that the secondary protocol session can bypass the load balancer. Do not manually edit the /etc/resolv.conf file. [3064658], This release implements a new Spring API that makes it possible to create pool partitions. The troubleshooting steps can also be applied to internal connections. Underscores (_) are not supported in server names.
