I'm having trouble cloning a repo on git. I've been trying for to days and have tried quite a few solutions (in most the problem was slightly different but seemed to apply) but nothing has done anything to make a difference.

I've tried switching off the anti-virus and firewall but that didn't help. I've also tried uninstalling and reinstalling the network adapter drivers (and restarting the computer) and that didn't work.

From what I understand it's a network issue somewhere as the remote server keeps hanging up but I'm not managing to get anywhere with the issue.

Using git clone -v --progress seemed to give the same output as git clone. Output from git clone -v --progress https://github.com/mit-cml/appinventor-sources.git

Cloning into 'appinventor-sources'...
POST git-upload-pack (gzip 1425 to 774 bytes)
remote: Counting objects: 41649, done.
remote: Compressing objects: 100% (7/7), done.
error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

I've now tried increasing the buffer again

git config --global http.postBuffer 1048576000

but still nothing.

I'm following the solution from The remote end hung up unexpectedly while git cloning for troubleshooting.

I resolved the same problem by this:

git config http.postBuffer 524288000

It might be because of the large size of repository and default buffer size of git so by doing above(on git bash), git buffer size will get increase.

Cheers!
