Can I use git protocol to push change to remote repo?

Hello,

I can clone a remote repo with git protocol, but I can't push my branch to origin repo with git protocol. If I use ssh protocol, I can push sccuessfully. I'm confused, can someone give me a guide on this? Can I use git protocol to push my branch to remote repo? If yes, how can I do ? Thank you for your help in advance !

Error info is as below:
 $ git push git://host.xz/testgit check_push
fatal: The remote end hung up unexpectedly
error: failed to push to 'git://host.xz/testgit'

Successful info with ssh protocol:
$ git push ssh://host.xz/testgit check_push
user's password:
updating 'refs/heads/check_push'
