Symptoms
When trying to push to Bitbucket using Git and https, the following errors are encountered
Counting objects: ###, done.Delta compression using up to # threads.Compressing objects: 100% (###/###), done.Writing objects: 100% (###/###), ##.## MiB | ##.## MiB/s, done.Total ### (delta 64), reused 0 (delta 0)error: RPC failed; result=55, HTTP code = 0fatal: The remote end hung up unexpectedlyfatal: The remote end hung up unexpectedly |
Diagnosis
The line that is relevant here is
error: RPC failed; result=55, HTTP code =0 |
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:
CURLE_SEND_ERROR (55) Failed sending network data.
Cause
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 the Bitbucket Support Team Troubleshoot
To help troubleshoot this issue, try running the push with the command
GIT_CURL_VERBOSE=1git push |
This will run the push command with the underlying libcurl library set to verbose mode. This will output a lot of data on the command line when running the push. Copy and paste the information output into a support ticket to help the Bitbucket team troubleshoot what
may be wrong in your specific case.

Workaround
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.

Resolution
There may not be a solution for all users who encounter this issue as it is network related and can be affected by a variety of factors outside of the Bitbucket site's control.
