epel on Centos 7

[ogniemi]

after I installed EPEL repos yum update hangs with no sense reason:

 One of the configured repositories failed (Extra Packages for Enterprise Linux 7 - x86_64),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

[highlight #73D216][root@centos7 yum.repos.d]# wget -q [URL unfurl="true"]http://download.fedoraproject.org/pub/epel/7/x86_64/repodata/repomd.xml[/URL]
[root@centos7 yum.repos.d]# echo $?
0[/highlight]
[root@centos7 yum.repos.d]# ls -al repomd.xml

[root@centos7 yum.repos.d]#

So, why yum gets stuck on the url and wget not?

[root@centos7 yum.repos.d]# yum upgrade ca-certificates --disablerepo=epel
No packages marked for update
[root@centos7 yum.repos.d]# yum update --disablerepo=epel
No packages marked for update
[root@centos7 yum.repos.d]# grep -e ^mirr -e ^baseurl -e enab -e ^\\[ epel*

[root@centos7 pluginconf.d]
# pwd
/etc/yum/pluginconf.d
[root@centos7 pluginconf.d]# grep ^enabled fastestmirror.conf

any clue what is going wrong in Centos 7? I don;t remember such issues in Centos 6.

of course I can download with wget packages from epel manually and install it with no issue, but why it does not work in yum?
