Getting 403 error in Ch02s04 lab step 6.1 & 6.3

I am unable to create a container image due to 401 Unauthorized access while connecting to https://registry.ocp4.example.com:8443

PS: After pausing and restarting the lab environment, it seems to have fixed itself. I could rerun the lab start command and the building now works.
