Not sure if the https errors are really related to the changes here. Tests seem not to work at all (https://testgrid.k8s.io/r/knative-own-testgrid/serving#https).

WDYT? @dprotaso @nak3

[nak3]

You are correct. HTTPS test is not stable now #14435

I think I don't have a power to approve though.

@dprotaso would you mind taking a look ^^

[dprotaso]

Added some minor comments that can be done in a follow up

[dprotaso]

Can you make a follow up issue so we don't forget to remove this file after the infra changes?

[dprotaso]
