Fitbit One "com.fitbit.HTTP error 500." Error when updating firmware from 6.46

[greencurrytofu]

I am trying to update my One device using the iOS app, but I am consistently receiving a 500 error. 

I have turned the bluetooth off and on.

I have restarted my One device 4 times.

@greencurrytofu Welcome to the Fitbit Community! Thanks for reporting the error message you are getting when trying to update Fitbit One.

By any chance did you deleted a previous account you had and paired your One with a new email?

No, I have not deleted a previous account. I have not paired my One with a new email.

Concerning the troubleshooting steps, as previously stated, I have rebooted my One device many times.

I also restarted my iPhone and this did not fix the problem.

The final instructions in the troubleshooting steps is to download the firmware using a computer. I don't know how to do this.
