  • Hi, did you manage to find a solution to this in the end? I am trying to setup OTP on my TZ300 device but I'm having the same issue. I've tried multiple email servers and always receive the same error. I know account credentials are correct as I can login on web mail apps. Error: SMTP Authentication Failed.
