There are several configuration/setup problems that can result in an inability to launch a HTML Access (Blast) connection successfully.

Problem

Solution

Browser is not HTML5 compliant

Check that the browser version is one cited in the requirements.

Pop-up blocker enabled

The browser's pop-up blocker could prevent opening the new window for a HTML Access connection. Make sure that the user disables the pop-up blocker for the Desktop Portal.

Windows firewall disabled

Make sure that the Windows Firewall is installed and running on the user's desktop. A disabled Windows Firewall will result in errors reported in the HTML Access logs.
