I think you need just copy the file 'nut-2.7.4.1.20210620-x86_64-1.txz' attached in my message to folder /boot/config/plugins/nut And reboot server, it may use latest version of nut instead of old one. If it not works this way, replace existing nut-2.7.4... file in folder /boot/config/plugins/nut by my file and reboot
