Answer 1

Well, this is caused by some bad network status or some large files included in your commit. In my case, I have tried after some mins, it worked.

So I suggest you should do push several times in some intervals, or increase buffer size and then try to push again?

git config --global http.postBuffer 15728640

Answer 2

After about 3 hours of trying, the problem was solved after using a VPN
