İ am trying to add Variscite DART-6UL board as client device on my mender production server. When I got this error for the first time, I disabled ntp and set the clock manually. I keep getting the same error even though the clock is correct.

Is there anyone who can give me an idea of what i can do ?

Thanks

I assume your production server date/time is up-to-date? and the expiry date-time in your certificate is some time in the future?

Yes production server date/time up to date and certificate is valid.

To narrow the problem you could try setting a timezone other than UTC temporarily on the device to see if its related to a date/time support in golang which I believe mender-client is written in.

Actually i solve the situation. When i command “systemctl status mender” there is no error at the begining, but later the same errors above looks after a while. Any suggestion ?

Thanks

as per my previous suggestion, try changing the timezone to narrow down the problem as i could depend on what libraries/ system resources are used by golang.
