Failed to download metadata for repo 'fedora-modular'

[jake12]

I’m trying to create an SSH key and GPG key for Git using this article: Using GIT in Qubes 4 with Split SSH and Split GPG - denis zanin github
I created an AppVM by cloning the vault and I just ran sudo dnf install qubes-gpg-split # but I’m receiving this error: Failed to download metadata for repo 'fedora-modular': Cannot prepare internal mirrorlist: Curl error: Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=fedora-modular-32&arch=86_64 [Could not resolve host: mirrors.fedoraproject.org]

I’m a beginner to using Qubes. Any help on solving this error would be really appreciated.
