Junos Pulse Failed to Connect

Recently the Juniper Networks Junos Pulse client software I use to connect to a work VPN stopped working on my MacBook Pro running OS X 10.8.5, aka "Mountain Lion". After the problem first occurred, whenever I started the Junos Pulse program which is at version 5.0.3, I would see a window with no connections listed whereas previously I would see the work VPN connection with a Connect button to the right of it. So I clicked on the plus sign, i.e. +, at the bottom left-hand corner of the window to add a new connection, since the client seemed to have "forgotten" the information for the VPN. I left the type set to "UAC or SSL-VPN" and put in the server URL, which was in the form of https://fqdn where fqdn is the fully qualified domain name (FQDN) for the VPN server. I then gave the connection a name in the "Name" field.

Junos Pulse - Server URL

But whenever I then clicked on the Connect or Add button in the Junos Pulse client, I would see the message below:

Junos Pulse

Failed to connect to the Juniper Unified Network Service.

Junos Pulse - Failed to Connect

I checked the log for the Junos Pulse VPN client software at /private/var/log/Juniper Networks/Logging/debuglog.log and saw many "'JamUI' Connection to UIModelService plugin failed - service may not be running" messages.

I had tried the steps at Junos Pulse VPN Client Issue on Mac OS X a couple of days ago when the problem first started, since I had been able to resolve a prior problem with the Junos Pulse client application with those steps. This time I entered just the commands below:

$ sudo launchctl load -w /Library/LaunchDaemons/net.juniper.AccessService.plist
Password:
$ launchctl load -w /Library/LaunchAgents/net.juniper.pulsetray.plist

I then saw the following in the JunOS Pulse window:

Junos Pulse Disconnected

When I clicked on the Connect button, I saw "Failed" appear in the Junos Pulse client window.

Junos Pulse Failed

When I clicked on the pencil icon, which appears to the right of the plus and minus signs at the bottom of the Junos Pulse client window, to edit the information for the VPN server, I saw the Name and Server URL fields were blank. The Save button was now appearing rather than the Add button, though. I filled in those fields with the information I had entered before and clicked on Connect.

Junos Pulse Save button available

I was then able to connect successfully to the VPN. I had to disconnect in order to be able to save the information. After disconnecting, I clicked on the pencil icon to edit it and chose Save.
