Happens after 1.10 rebase landed, seems like the scaler need PATCH or retry mechanism:

@bparees all the build flakes I saw today seems to be related to this (unable to push to registry, I guess because registry failed to scale up, just FYI)

@wozniakjan fyi in case this is showing up in our extended builds tests too.

This should be now fixes as @deads2k #19275 merged.
