OTP Issues with several users

Hello,

sice some days we have the problem that with some users (will be more and more) OTP auth is failing:

-> oath_totp_validate() failed for tokenid xxxxxxxxxxxxxxxxxxxxxx with error The OTP is not valid

- OTP was working fine all the time before issues
- the users and the firewall have correct time and date
- when checking time offset the offset is too big to displayed or extreme high
- the problem exist with old Sophos Authenticator app and Microsoft Authenticator on iOS 17.6
- the problem seems not to depend on App or Phone (other OTP codes are working on the same phone/app)

When delete and autocreate new tokens for the users it will work again.

Anybody has an idea what's going on? Bug?
Is there any reason (a working) OTP is not working anymore someday?
