Check the time on your computer is accurate

Already manually ran ntpd (Redcore has the KDE GUI setting to sync to internet time greyed out), and trying to access me menus on another device had the same result.
OK, checking....
I dont see anything wrong, usually this error is caused by time being really out of sync on the machine, what login system are you using? If you're using NIP7 maybe you denied access to sign some NIP-98 auth events.
