Fail OTP after several days or months

Question

I have activated the OTP in an XG XG330 and every XX days or mounths I have to reset the QR code as it starts to fail, people cannot connect to the VPN or access the user portal until I delete them and recreate the QR code, once it is reconfigured on their devices, everything works correctly again for XX days or mounths 
 
 Thank you for your help
