pac pcf push underlying connection closed issue

[beef9r]

Hi,

We're running pac pcf push behind a company proxy. Everything is smooth so far and works as expected until the "Publish All customizations" task. pac cli is giving us the error below but runs in behind in our environment and finishes there without errors.

The whole thing is running on azure dev ops self hosted agents.

npm install
npm run build -- --buildMode production
pac pcf push --solution-unique-name solutionname
