TiQR Token fails to authenticate

Hi guys,

I am currently looking at TiQR token. I set up policy as in this video : https://www.youtube.com/watch?v=mBQG0WX4Rgo&t=155s . After enrolling a TiQR token and trying to login , I encountered this problem with little detail. My current version of privacyIDEA is 2.23. I appreciate any help on this .
