Verification code is not matched in Staging environment

[PirunSeng]

I've followed #46 Two Factor Authentication episode of DriftingRuby and I can get the TFA works well in my development environment. Unluckily, there is a strange behavior when I deploy my feature to Staging environment.

Here is my QRCode generator:
qr = RQRCode::QRCode.new(resource.provisioning_uri, level: :h)

The rest of the implementation are the same as described in the epicode.

A strange thing is that the QR code looks differently between development and staging environment. The problem is that I can scan the QR code in staging environment, but when I use that code to verify, it is always not matched.

Can somebody figure whether this is a bug of Active Model OTP or RQRCode gem?

I'm using:

gem 'rails', '4.2.2'
gem 'devise', '~> 3.5', '>= 3.5.2'
gem 'active_model_otp', '~> 1.2'
gem 'rqrcode', '~> 0.10.1'

@PirunSeng Is there any update? How did you fix it?

This issue was posted more than 2 years back, but still it's opened. Same issue we are also facing. It will be beneficial if someone looks into it.
