Horizon View 5.2 Common HTML5 Access Issues

I run into a number of minor issues when I was configuring Horizon View 5.2 HTML access, so thought it would be a good idea to get my frustrations, I mean fixes down in a blog post.

1. Connection Server

Check your Connection Server settings, as URL’s are reset after the upgrade.  In specific make sure that

• HTTP(S) Secure Tunnel URL is correct e.g. https://vmfocus.no-ip.org:443
• PCoIP Secure Gateway is correct (note this can be the internal IP address if you are using a Security Server)
• Blast Secure Gateway URL is correct e.g. https://vmfocus.no-ip.org:8443

2. Security Server

Check your Connection Server settings, as URL’s are reset after the upgrade.  In specific make sure that

• HTTP(S) Secure Tunnel URL is correct e.g. https://vmfocus.no-ip.org:443
• PCoIP Secure Gateway is correct e.g. 80.80.80.80:4172
• Blast Secure Gateway URL is correct e.g. https://vmfocus.no-ip.org:8443

3. View Desktop

When connecting to the View Desktop if you receive error message ‘the display protocol for this desktop is currently not available.  Please contact your system administrator’.

Double check to make sure the VMware Blast service is running on your target View Desktop and that you can telnet to the View Desktop on port 22443 as this is the  port that it listens for connections on.

If you close your Horizon View HTML5 session without logging out and then try to reconnect again you might see the error message ‘All available desktop sources for this desktop are currently busy. Please try connecting to this desktop again later, contact your system administrator.

To rectify this, log out and then log back in again.

4. Firewall

You can authenticate correctly to your View Connection/Security Server however when you go to launch your desktop, it sits on sending request and times out.

Check your NAT rules on your Firewall to make sure that Port 8443 is NAT’d to your Horizon View Security Server.  To double check this telnet to your external IP address on Port 8443.
