    Hi Julian,

    This sounds like there is an issue with the clocks not being in sync. Could you please check whether you can update the system time of your client machine?

    Cheers,
    Matthias

    Hi Matthias, thanks for your response. Is a 4 minutes delay acceptable?

    No, I don't think so. All kinds of systems can get confused with such a large time discrepancy. As a rule of thumb, I'd say everything larger than one second is typically not acceptable. The good thing is that if you are using a WLS license, you also have internet access, so you can always sync the machine clock with an internet clock.

    Cheers,
    Matthias
