I have faced this problem too, my internet connection is 512kbps, but
before dnf in the memorables yum days I never had this kind of
problems.

Did you added this lines to the dnf.conf configuration file?

keepcache=true # This config line adds the capability of keeping the
cache and the dowloaded packages on the cache if something got stuck
and you need to restart it without having to download the already
downloaded packages again.

deltarpm=true # This config line will retrieve delta rpm's packages
for download updates instead of downloading the full packages, it save
time and data if you are using 3G or LTE connections.

fastestmirror=true # This will force dnf to keep a cache of the most
efficience mirrors.

To add it:
su -c "echo 'keepcache=true' >> /etc/dnf/dnf.conf"
su -c "echo 'deltarpm=true' >> /etc/dnf/dnf.conf"
su -c "echo 'fastestmirror=true' >> /etc/dnf/dnf.conf"

I must confess that even adding this to my dnf.conf file sometimes the
problem back or appear.

Also there is a bug about dnf-make cache service, it tries to run on
the boot up, get stuck and if the user try to run a dnf update cause
this annoying problem.

You may try this:
1. Kill the dnf-makecache process

2. Clean all the dnf cache:
su -c "dnf clean all"

3. And then make the cache:
su -c "dnf makecache"

If you are under a slow internet connection make sure that there is
not any other process that might drain your bandwidth.
