fatal: the remote end hung up unexpectedly

Question

Hey guys!
Two people in our team facing issues when pushing a word document "fatal: the remote end hung up unexpectedly".

When someone(except those two people) else pushes the same document and they pull and push,  it works.

Here is the full message:

POST git-receive-pack (chunked)

send-pack: unexpected disconnect while reading sideband packet

fatal: the remote end hung up unexpectedly

Everything up-to-date

Note: 1.)we use our local GIT server.

2.) the file is "small"

3.) MacOS

Any thoughts?

Solved by increasing the Git buffer size to the largest individual file size of the repo:

* git config --global http.postBuffer 157286400
