CentOS 6.8 Yum cannot connect?

[TrevorH]

baseurl= is meant to be commented as it uses the mirrorlist= list instead. The proxy line is weird and probably shouldn't be there.

yum.repos.d]# telnet mirrorlist.centos.org 80
Trying 85.236.43.108...
Connected to mirrorlist.centos.org.

I can reach the destination on port 80 actually...

commented all baseurl and uncommented mirrorlist ones. still no difference

Yum points me to some error with base repo. cannot find valid baseurl

Output of yum repolist says i have problems in epel and elrepo.... but these repo files are identical to other servers that work fine

[sancho85]

The Problem is solved.

1. we had problems on firewall that was blocking access to repo.
2. something was wrong with links inside the repo files. Solved it via copying these file from identical servers.
