oc start-build is timing out on Red Hat OpenShift Container Platform

Issue

• When we start a build with oc start-build, we get a lot of Error from server (Timeout): Timeout: request did not complete within allowed duration. Running the command with loglevel=10 is reporting the below error.

$ oc start-build abcdefg-0990-4dcc-bd9b-f400949bd777 --wait -o name -n build --loglevel=10
