Unable to register Eddystone Beacon on Beacon Tools

Hey guys, I am trying to register my Eddystone Beacon with Beacon Tools. However, it says “Failed to connect. Do you need to push a button on the beacon?”

After I clicked the button on my Beacon, new error message appears:
46519611_2281818048769221_8576914531786162176_n

Anyone knows the solution to this problem?
