There are several common mistakes that cause the Palo Alto Networks VPN to be flaky or not work at all, and I thought I would list a couple of them to make everyone’s life easier.
- When installing on a 64 bit client machine, be sure that 64-bit version of Java is installed, and also be sure that you are using a 64-bit browser during installation (e.g Internet Explorer 64-bit).
- Be sure to remove all other VPN clients as they generally interfere (specifically Cisco and SonicWALL). For specifics, see my post here.
- NetConnect will not install with Java 1.5 or earlier. Java 1.6 or later is required.
