[Shotwell] unable to connect to facebook

[Alex Insaurralde]

Hi,

I just recently installed Shotwell and I am very impressed with the features. One feature I tried to use is the "publish" to Facebook.  I entered my email and password but got this error message.  I tried several times to reconnect but I get the same message. Any ideas on what to do next?

I've attached a png of the error message.

Thanks,

Alex
