During 2FA registration authentication code not accepting by Redmine Application

Added by KUNTAL MONDAL about 22 hours ago

We have installed Redmine 6.1.2 on RHEL and completed all the required configuration steps. However, we are facing challenges while enabling two-factor authentication (2FA). During registration with an authenticator app, Redmine does not accept the generated verification code and displays the error: “Code is invalid or outdated.”
Kindly advise on the possible cause of this issue and how it can be resolved.
