Updating to latest image via ssh stuck at pull

Hello guys,
I tried to update discourse to latest version via ssh got stuck at pull request, so i closed my terminal and I updated to latest version via one click update in my browser.The update was sucessful. Later I sshed again into my server and tried to rebuild discourse app again, but still the same. Rebuild is stuck!! Its been half an hour.

Any guess ??

I suspect slow network speed or poor connectivity to github from Your server provider’s network.
