The issue here was specific to user’s local machine time. It was not synced with the world clock & hence it was 1 hour ahead of the actual time. This was causing the JWT to be considered as expired. We asked the user to check the time on the local machine on this website: https://time.is and it was clearly showing the difference in there.
Issue got resolved when the user synced their machine clocks with the OS time settings (eg: Apple clock auto set).
