Recently, I discovered that Digital Guardian (corporate security software) appears to block the Enpass Extensions from communicating with the Enpass Application. I originally thought the issue was with the Enpass software about a month ago and then they started working again, but I received an update to the security software and the behavior is back. Not sure if you can work with Digital Guardian to recognize the function as legitimate or look into an alternate method. For now, I will have to use Enpass without the extensions.
