Capsule installer failed

Hi, it seems to be more like an yum repo issue, here is what I get when I
tried to run capsule installer:
capsule DCU [/etc/yum.repos.d] 190# capsule-installer --parent-fqdn
"foreman.anim.odw.com.cn" --register-in-foreman "true"
–foreman-oauth-key "3kjSDNem4ueGb7yAkAMT9uAiuYbUW69P"
–foreman-oauth-secret "j5TJ7toRtaukQRsdz2cXGG6tExmCXHin"
–pulp-oauth-secret "2KrtmF9Gch9CdWCMgnXWZLEjJdAMQnpi" --certs-tar
"~/capsule.
dcu.anim.odw.com.cn-certs.tar" --puppet "true" --puppetca "true" --pulp
"true" --tftp "true"
Execution of '/usr/bin/yum -d 0 -e 0 -y list pulp-katello' returned 1:

if I ran yum list, I got:
capsule DCU [/etc/yum.repos.d] 191# yum list
Loaded plugins: priorities, product-id, security, subscription-manager
https://www.softwarecollections.org/repos/rhscl/ruby193/epel-6-x86_64/repodata/repomd.xml:
[Errno 14] PYCURL ERROR 7 - "couldn't connect to host"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository:
rhscl-ruby193-epel-6-x86_64. Please verify its path and try again

it seems that this server is down, any one know anything about that? I
think the capsule install failed was due to this issue.

Thanks
