Pods not resolving several host

[jamorales85]

Describe the bug
Pods don't resolve several external links.

argocd-server-7cd5794cc5-khh8q:/tmp$ git clone https://github.com/argoproj/argocd-example-apps.git
Cloning into 'argocd-example-apps'...
fatal: unable to access 'https://github.com/argoproj/argocd-example-apps.git/': Could not resolve host: github.com

Version
4.8.0-0.okd-2021-10-24-061736

How reproducible

argocd-server-7cd5794cc5-khh8q:/tmp$ git clone https://github.com/argoproj/argocd-example-apps.git
Cloning into 'argocd-example-apps'...
fatal: unable to access 'https://github.com/argoproj/argocd-example-apps.git/': Could not resolve host: github.com

Notes
Workaround: Pods node-resolver-* from openshift-dns namespace has the next error:

[root@okd4-compute-1 /]# host www.github.com
host: parse of /etc/resolv.conf failed
[root@okd4-compute-1 /]# cat /etc/resolv.conf 
search 
nameserver mydns.com

If I fix the /etc/resolv.conf in those pods, the cluster works properly.
