You might experience connection problems between View Client and View Connection Server.

If the connectivity between View Client and a View Connection Server instance fails, you see one of the following View Client errors:

A secure connection to the server 'servername' cannot be established.

The View Connection Server connection failed.

Opening a desktop might also fail after contacting a View Connection Server instance and obtaining a list of available desktops.

Connectivity problems between View Client and a View Connection Server instance can occur for different reasons.

Incorrect network proxy or firewall settings on View Client.

Lookup failure for the DNS name of the View Connection Server host when setting up a secure connection.

Try the following solutions in sequence. If a solution does not resolve the issue, try the next one.

Use a browser to access the View Connection Server instance by using HTTP or HTTPS.

If you do not see the login page, apply general network troubleshooting techniques to resolve the issue.

Enter valid credentials on the login page.

If you receive an error message about being unable to start the secure connection, the most likely reason is that View Client (or proxy server, if configured) is unable to resolve the DNS name of the View Connection Server host. Configure the host to provide its IP address rather than its FQDN when it directs View Client to open a secure connection.

The external URL is updated immediately. You do not need to restart the View Connection Server service for the change to take effect.

If the preceding solution does not resolve the issue, restart the View Connection Server instance.
