I'm facing a ftp.dell.com error, when I try to update the server firmware from Lifecycle Controller. I started by downloading the Platform Specific Bootable ISO (PER720XD_BOOTABLE_21.12.00.24.iso) and ran it, it updated everything to latest versions. When I press F10 to enter the LC and go to Firmware update section, I only have the FTP option, no HTTP or HTTPS. Even if I change the address to downloads.dell.com, I get an error.

What is the proper fix?
