Resolution

Multiple reasons can explain your repositories are not reachable.

Follow at first the below KCS:
RHEL 7 to RHEL 8 LEAPP Upgrade Failing When Using Red Hat Satellite

And then check dnf version 4.0.9 (from RHEL 7 extras) is able to install dnf version 4.7 from your el8 repositories, as Leapp does.

Don't forget to adapt the URL (domain and path), the SSL certificate & key ("XXX"), and the $releasever (here 8.8) to your environment.

# cat << EOF > /etc/yum.repos.d/test.repo
[test]
name = test
baseurl = https://<URL>/pulp/repos/Default_Organization/Library/content/dist/rhel8/8.8/x86_64/baseos/os
enabled = 0
gpgcheck = 0
sslverify = 1
sslcacert = /etc/rhsm/ca/katello-server-ca.pem
sslclientkey = /etc/pki/entitlement/XXX-key.pem
sslclientcert = /etc/pki/entitlement/XXX.pem
EOF

# dnf clean all
# rm -rf /var/cache/dnf/*
# mkdir /var/lib/leapp/test
# dnf install -v -y --releasever 8.8 --installroot=/var/lib/leapp/test --disablerepo '*' --enablerepo test dnf

If it does not work, the issue likely comes from your Satellite server. On the client side, please check /var/log/dnf.log and /var/log/dnf.librepo.log for more details.
