Git “efrror: RPC failed; result=55, HTTP code = 0” on push

I’ve spent all day on this one and could really use some help. When I try to push a relatively large commit,

Writing objects: 100% (21/21), 908.07 KiB | 0 bytes/s, done.
Total 21 (delta 17), reused 0 (delta 0)

git takes a very long time to respond and then gives

  • Git sparse checkout for simple web deployment
  • Embedded linux/android kernel development workflow
  • Change branch-off point
  • Search all branches created by a user in a GitHub repository
  • Git magic references
  • “Bottom up” rationale for how Git works
  • "efrror: RPC failed; result=55, HTTP code = 0 
    atal: The remote end hung up unexpectedly
    fatal: The remote end hung up unexpectedly
    Everything up-to-date"

    I have searched this error code, and the most likely solution seems to be extending the buffer size

    git config http.postBuffer 524288000

    I have tried this solution with no success. After VonC’s suggestion, I tried switching from http to ssh. From ssh, I get a long hang up at the same point. Eventually, the following error message appears

    Read from remote host Connection reset by peer
    fatal: The remote end hung up unexpectedly
    fatal: The remote end hung up unexpectedly

    Could this be a router issue? I have tried pushing from a different computer on a different network and am able to do so successfully.

    I am away from my Linux machine on a Windows host and using the terrible poshGit Windows PowerShell interface.

    Any ideas??

  • vim syntax highlighting for git commit messages - custom commentchar
  • Git “unable to determine absolute path of git directory”
  • How can I populate the Git commit ID into a file when I commit?
  • Git: post-receive email hook, including diff patches?
  • Auto deployment with gitlab
  • Fatal: not a git repository - after BSoD

    You can follow the debug advices from the BitBucket article:

    Specifically, the ‘result=55‘ portion.
    This is the error code coming from libcurl, the underlying library used in http communications with Git. From the libcurl documentation, a result code of 55 means:

        Failed sending network data.


    This can be caused by a variety of network related issues or even the Bitbucket service itself. It essentially means that the connection was dropped unexpectedly. Things to check would be to attempt the push from a machine on a ‘clean’ network outside of any corporate firewalls or proxies. Check all proxy servers to ensure they are properly moving SSL data and are fully permitted to complete.

    To help troubleshoot this issue, try running the push with the command

    GIT_CURL_VERBOSE=1 git push


    If after checking all connections and proxy configurations the connection still fails consistently, please report the information above to support. Then switch to SSH. We have a guide to getting it setup for Git at Set up SSH for Git. If you should run into any configuration issues while setting up SSH, please refer to our SSH Troubleshooting guide.

    I experienced the issue due to a misconfiguration, where I pointed to a remote prefixed with http:// instead of https:// the answer hinted on SSL and this helped me to a solution for my issue.

    So my remote configuration should be written:

    $ git remote add origin


    $ git remote add origin

    Take care,
