Docker 推送给出“blob 上传未知”

Question

I am using TFS 2017 builds to push a docker image to Azure container registry.

Build Machine: Ubuntu 16.04 TFS 2017 update 3

the push functionality used to be working fine, suddenly and out of nowhere it started giving an error while trying to upload the image:

 /usr/bin/docker login -u ******** -p ******** sdpacr.azurecr.io
 Login Succeeded

 /usr/bin/docker push sdpacr.azurecr.io/calendarmanagement:7787
 The push refers to a repository [sdpacr.azurecr.io/calendarmanagement]

 /usr/bin/docker logout sdpacr.azurecr.io
 Remove login credentials for sdpacr.azurecr.io

I have set up another build agent on windows and installed Docker for windows and it seems to be working fine.

what am I missing? and how can I actually retrieve more info about this error?
