Git Push failed; RPC failed; result=56 :/

After getting a legacy project into Git version control on my local machine today, I was ready to push up to the repository created in our on-site hosted Git server.

But, I kept getting the following error message:

error: RPC failed; result=56, HTTP code = 0 
fatal: The remote end hung up unexpectedly
Failing at PowerShell command prompt
Failing at PowerShell command prompt

So, I thought – maybe its just poshgit playing up? Lets check in WebStorm:

Failing in WebStorm too!

Hmmm… to the search engine!

To get Git in use at my current contract, I installed GitBlit on the available development server (would have preferred to use Github or Stash, but it had to be on-site hosted only and have very little cost implications).

I came across a GitBlit issue raised by a user getting the same error – GitBlit Issue 162.

This advises to increase the http.postBuffer value in the Git config:

git config http.postBuffer 524288000

Which got the push working perfectly:


Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests. —
