Description of problem:

Since I updated from openshift-clients-4.6.0-202006250705.p0 to the lasted version using the Brew package  when I attempt to login into a cluster I do not have anymore the interactive question to trust or not the clusters I.E.:

Server https://localhost:8443: https://openshift.example.com:6443 
The server uses a certificate signed by an unknown authority.
You can bypass the certificate check, but any data you send to the server could be intercepted by others.
Use insecure connections? (y/n): y 

but it goes directly on: 

error: tls: failed to verify certificate: x509: certificate signed by unknown authority

Only adding the flag --insecure-skip-tls-verify=true allow me to connect which is more painful than just replying to the interacting question.

I can confirm that this is a bug present on Client Version: 4.13.2 as when I downgrade the package version to the previous 4.6.0 it when back to work as expected.
