I am facing a problem with authenticating with 2FA on just one windows machine. For a week it worked fine but after that it just says failed to authenticate even when I put in the correct passcode and even before it expires. I checked the server logs and this is what it says. The same user works fine on all laptops except one. I tried reinstalling the client and creating a new user but nothing seems to work. Can u tell what the problem is??

This is most likely an incorrect timezone on either the server or the client. The time may appear to be correct but the code will convert the current time into UTC. It does this by using the configured timezone to offset the time to UTC. If the time doesn’t match the timezone this offset will be incorrect causing timestamp or OTP authentication errors. The server and client don’t need to have the same timezone but the time must match the correct time for the configured timezone.
