I have a Azure DevOps pipeline that attempts to build and pushe a Docker container to the Azure ACR from an on-prem 2016 server. We get a 502 error when attempting to push the image via Docker BuildAndPush task. It looks like the build part succeeds but the push portion never really connects to the server. It just keeps trying until the server times-out and closes the connection. Cannot post the full log due to length, abbreviated log follows...

You got the 502 error, it means you cannot connect to the ACR server. The possible reason is that you set the wrong image name. To push images to ACR, you need to set the image names like
yourACR.azurecr.io/imageName:tag, and then push it with the ACR credential.
