    SOLVED: PVE certificate expires in more than 2 years

    Hi, For some reason PVE tries to update my custom certificate and predictably fails with truncating the cert file which leads to inaccessible web interface: # pveversion pve-manager/6.2-15/48bd51b6 (running kernel: 5.4.65-1-pve) # systemctl status pve-daily-update.service ... Nov 17 03:14:33...

    Feature request: VM replication over Syncthing
