there is a high possibility that your system has an incorrect date and time set (system clock is behind).
Check the system time on Almalinux
To check if the current date and time is showing up correctly on your AlmaLinux server, please use the following command:
timedatectl statusDisable automatic time synchronization
In order to be able to change the system time immediately, you must first disable the automatic time synchronization. Use this command to ensure that the automatic time sync is disabled:
sudo timedatectl set-ntp falseSet a correct system date and time
Use this command to set a correct system time. Replace the YYYY-MM-DD HH:MM:SS with the current date and time according to the given format (e.g. 2027-05-05 21:58:05):
sudo timedatectl set-time "YYYY-MM-DD HH:MM:SS"Enable back the automatic time synchronization
Use this command to enable back the automatic time synchronization. Leave it disabled only if you face problems with it.
sudo timedatectl set-ntp true
