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.
n
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.
Solution
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
Troubleshooting View Server Certificate Revocation
Checking
A security server or a View Connection Server instance that is used for secure Horizon Client connections
might show as red in View Administrator if certificate revocation checking cannot be performed on the
server's SSL certificate.
Problem
A security server or View Connection Server icon is red on the View Administrator dashboard. The View
server's status shows the following message: Server's certificate cannot be checked.
Cause
Certificate revocation checking might fail if your organization uses a proxy server for Internet access, or if
a View Connection Server instance cannot reach the servers that provide revocation checking because of
firewalls or other controls.
