[Spacewalk-list] update to spacewalk 2.8 failed because cannot access spacewalk repo

[Jérôme Meyer]

Hi Team,

I'm trying to installed the last version of spacewalk 2.8 as describe in https://github.com/spacewalkproject/spacewalk/wiki/HowToUpgrade

Following error appears with the spacewalk repo, please see below.
I'm tried in many ways to escape it or to resolv it without solution.
Has anyone already had this problem? Or has someone an idea how to resolv it?
Other link to CentOS and so are ok...

Check up:
==============

nslookup and check through browser is ok but unreacheable through ping.

Config.:

It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.
