Bluetooth error domain 18

Hello! I cannot update my blaze because this error appears...I have updated the app to the 2.40 version, but it's still impossible to solve the problem. Can you help me, please?

Hi again,

i updated the app to the 2.40 version and it's still not working...i have also tried to restart my blaze as a new device in the app but when I introduce the code it gets blocked...doesn't do anything...

Thanks for the update and the screenshot @laiapons.

Have you tried to restart your phone? If you haven't, I recommend trying this procedure. Then uninstall and reinstall the Fitbit app. 

Please, keep me posted.

I have been unsuccessful to get my Fitbit blaze to update with my iPhone 6s.  I keep getting the same domain error 18. I've done everything that has been mentioned---newest version of the app, uninstall and reinstall the app, restarted my iPhone, restarted my tracker, turning blue tooth off and on, I'm on a good wifi network, tried setting up as a new blaze, my tracker is full charged...is there anyway I can fix this? Anyone else having issues after trying all the mentioned steps? When I try and set up a new blaze it won't connect to the iPhone. It says "are you having trouble? Isn't your Fitbit charged? Are you on a wifi network? Are you connected to Bluetooth?" And the answer is yes to all three. One time I was able to get to the screen where you validate with the number that pops up on your blaze, but then it locked up the screen.
