It seemed the logon user does not have permission to access file /etc/letsencrypt/live/domain.org/Cert-Windows.pfx, please try copy it to user home then download it again:
sudo cp /etc/letsencrypt/live/domain.org/Cert-Windows.pfx ~/
cd ~/
ls Cert-Windows.pfx
Hi,
thank you for your return. Yes, that is what I did to make it to work, but I need to do every single time that I need to work with a file/folder that the owner is root.
Can the download/upload run with sudo ?
