Parallel dnf update mirror is too slow and fails with timeout error
Make sure the scheduled metadata update timer is enabled and armed:

systemctl enable --now dnf-makecache.timer
If you use dnf as an unprivileged user (say, when searching for packages), use dnf -C so that it uses the system cache rather than your own user's cache.

I also set:

timeout=10
minrate=50000
in dnf.conf so it's somewhat more eager to give up on a slow mirror.
