My first attempt did not work, so I deleted the device from OBiTALK and did a factory reset on the OBi200. I then disabled DHCP and set a static IP of 192.168.0.120. Chrome can talk to it and the OBi Echo Test works.
So I go through the OBiTALK Add Device steps, confirm that OBiTALK can access my Google account but it sits there with the spinning dots in configuration for a long time and then quits.
