yum install/update does not work with "nic.funet.fi" yum remote repository and a callback aborted error is thrown

When configuring a yum repository to the below yum repository endpoint:
http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/epel/7Server/x86_64

yum install/update would not work and the below error is thrown:

https://admin:<api-key>@mohammadt.jfrog.io/mohammadt/rpm/7Server/x86_64/repodata/f2f5ddd4101a588a7c6eb60e20c45756b87e8123994fe1b3f0116a57ef74ce89-comps-Everything.x86_64.xml.gz: [Errno 14] curl#63 - "Callback aborted"ETA

Seems like this error is thrown, because we extract the content of the file: f2f5ddd4101a588a7c6eb60e20c45756b87e8123994fe1b3f0116a57ef74ce89-comps-Everything.x86_64.xml.gz, while the client does not expect it to be extracted.

If we will try to download this file directly from the remote endpoint:
$ curl http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/epel/7Server/x86_64/repodata/f2f5ddd4101a588a7c6eb60e20c45756b87e8123994fe1b3f0116a57ef74ce89-comps-Everything.x86_64.xml.gz -O

And then though Artifactory
$ curl https://admin:<api-key>@mohammadt.jfrog.io/mohammadt/rpm/7Server/x86_64/repodata/f2f5ddd4101a588a7c6eb60e20c45756b87e8123994fe1b3f0116a57ef74ce89-comps-Everything.x86_64.xml.gz -O

We will see that the file from the endpoint is compressed and from Artifactory is extracted.

Steps to reproduce:
1. create remote yum repo with the below URL:
http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/epel/

2. create this file /etc/yum.repos.d/artifactory.repo with the below content:
[Artifactory]
name=Artifactory
baseurl=http://<ARTIFACTORY_URL>/artifactory/rpm/7Server/x86_64/
enabled=1
gpgcheck=0

3. run $yum update

4. you will get the callback aborted error.
