Now when yous enable proxy, internet repo works (via proxy) and local patching server repo won't piece of work. Since it tries to reach a local patching server over the internet and couldn't do it (via proxy). If yous disable proxy, your local patching repo will work and net repo won't.

In such a case, you lot need a local repo to featherbed proxy and internet repo should get through the proxy. Here you can define local server FQDN/IP in Ignore Hosts or No Proxy Domains as I explained before.

From CLI, you can edit file /etc/sysconfig/proxy add entry in below line –

## Type:        string(localhost) ## Default:     localhost # # Example: NO_PROXY="world wide web.me.de, do.chief, localhost" # NO_PROXY="localhost, 127.0.0.1, patchingsvr.kt.com"
