3.77.1 fails on push to hosted docker registry

[pedroosorio]

I've recently upgraded from 3.75.1 to 3.77.1 only to find that i could no longer push to my internal docker registry. I've redeployed (from scratch) several times, and out of those, it succeeded one.

Then i did an upgrade test from 3.75 -> 3.76 -> 3.77. It indeed only fails in 3.77. Copying an artifact using regctl
