Ubuntu 16.04, bluez 5.41, can't connect

Hi all, hoping for some help so I can get cracking on some preojects.

Having an issue connecting to my puck via chrome:

1. I open the web IDE
   
2. I click connect and choose Web bluetooth
   
3. My puck shows, and I can attempt to connect.
   
4. That fails. Console says "Connection failed for unknown reason"
   
5. The puck will now not show up in the list of bluetooth devices I can connect to through the site until I reboot my machine. Rebooting the BT service alone does nothing.
   
   

The puck works fine on my android tablet, but obviously I'd rather code on something a bit more friendly.

Any ideas?
