A security server might not be working if it failed to pair successfully with a Connection Server instance.

Problem

The following security server issues might occur if a security server failed to pair with Connection Server:

  • When you try to install the security server a second time, the security server cannot connect to Connection Server.

  • Horizon Client cannot connect to Horizon 7. The following error message appears: The View Connection Server authentication failed. No gateway is available to provide a secure connection to a desktop. Contact your network administrator.

  • The security server is displayed in the Horizon Administrator dashboard as Down.

Cause

This problem can occur if you started to install a security server and the attempt was cancelled or otherwise aborted after you entered a security server pairing password.

Results

If you intend to keep the security server in your Horizon 7 environment, take these steps:

  1. In Horizon Administrator, select View Configuration > Servers.

  2. On the Security Servers tab, select a security server, select Prepare for Upgrade or Reinstallation from the More Commands drop-down menu, and click OK.

  3. On the Connection Servers tab, select the Connection Server instance that you want to pair with the security server, select Specify Security Server Pairing Password from the More Commands drop-down menu, type a password, and click OK.

  4. Install the security server again.

If you intend to remove the security server entry from your Horizon 7 environment, run the vdmadmin -S command.

For example: vdmadmin -S -r -s security_server_name
