Unfortunately, it merely had a workaround to the problem: use Firefox… Avoiding the fat client About ten minutes later JNC silently quit again. Again I was able to access sites behind the VPN.

I noticed that JNC was not running! I fired it back up and it connected as expected. After about ten minutes, I attempted to connect to a site behind the VPN and the site did not load. Upon following these steps and attempting to connect to JNC, the VPN connected as expected! Wow, way too much work just to get on the VPN.

Under “Configured websites” select the Allow drop-down from your VPN URL.

Under “Internet plug-ins” > “Website Settings…”.

Reading through the comments, someone suggested modifying the settings of the Java JNC plugin with Safari so that it did not have to run in Safari’s sandbox. I consulted Google again and came across this post.

Next, I was presented with a different error message: An error occurred while extracting one of the Network Connect components Upon doing so and restarting my MBP, the error message was gone. A quick Google search turned up this post, which suggested installing the Java package available here. I was confused by this as I had already installed the latest version of Java 8 and the Java test confirmed my browser was working as expected. When I attempted to connect to JNC, I was greeted with the following error message: To view this web content, you need to install the Java Runtime Environment. While configuring my MBP, I decided to give Safari another shot as I had not used the browser in a long time. UPDATE: Well look at that, appears I missed the announcement: Chrome is now 64-bit on Mac and JNC now works through Chrome! Thanks for the tip! Issues with Safari As such, I typically use Firefox to get on my JNC VPN and then Chrome for everything else. One of the first problems I experienced with JNC is that I cannot use it with Chrome as JNC requires a 64-bit web browser and the production version of Chrome is still 32-bit. On my MBP I use the Chrome web browser (I have an Android phone). In this post, I would like to talk about the problems I experienced attempting to connect to a Juniper Network Connect (called JNC throughout the rest of this post) VPN and how I was able to get it resolved. In addition, it brought up some old issues I had experienced and gave me a chance to fix them and document them. Configuring a different laptop gave me the opportunity to try out some new/updated applications and see if I could find more ways to be productive (I will cover this in a future post). While it was in the Genius Bar, I dug up an old Macbook Pro (called MBP throughout the rest of this post) and began to configure it so I could use it for work. Recently my laptop decided it no longer wanted to start.
