git clone error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054

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!

I had the same issue, and I have solved it by changing my net connection. In fact, my last internet connection was too slow (45 kbit/s). So you should try again with a faster net connection.

I had the same problem, and @ingyhere 's answer solved my problem .
follow his instructions told in his answer here.

git config --global core.compression 0
git clone --depth 1 <repo_URI>
# cd to your newly created directory
git fetch --unshallow 
git pull --all

you need to increase the buffer size (it's due to the large repository size), so you have to increase it

git config http.postBuffer 524288000

Althought you must have an initializd repository, just porceed as the following

git init
git config http.postBuffer 524288000
git remote add origin <REPO URL>
git pull origin master
