Not able to push an ALpine based image to docker hub

Hi,
I have built an image using Alpine. My image has Alpine OS and packages like Java, APache-ant insatlled.
After this I tried pushing the image to docker hub but it stops after certain limit. Please note that I have built this image using cmd line and not through Dockerfile. I did not face any issue even when committing the image.

After this point, there is no improvement.
Any help is appreciated!
