Squawker server seems to be down

[apex39]

[squawkerfcmserver.udacity.com](Squawker server) seems to be down - I cannot receive any of the messages sent.

I have just checked and it works for sending Squawk to a Single Device but I am not receiving Instructor's Squawk. Anyone knows why? I tested with the solution code provided.

I also cannot receive Squawks from Instructors but it works for sending to a Single device.

Same, cannot receive message from instructor.
