Initial Git push of large project fails- VPN Setting?

Question

Using a development IDE, an initial Git push fails with the following error message-

"Failed to write chunk." ...or... "Failed to write chunk footer." ...or... "Failed to write chunk header."

...then...

"The connection with the server was terminated abnormally"

I am over VPN to a VM. Fellow team member with same development IDE and same project successfully completes the initial Git push. They do not use a VPN/VM.

If I use TortoiseGit (same underlying Git client to VM via VPN), the initial push succeeds. In its displayed log, it seems that TortoiseGit is compressing the project. The development IDE may be compressing, or not. It does not disclose that in its output log.

One similar posting here on Stackoverflow intimated that VPN settings need to be modified. If so, what are those setting to look for?

Please advise. Thank you.
