As long as the Continua CI Server service is shutdown, then you can delete the contents of the repository cache folder and then run a manual
git clone. When the service is restarted it will continue to fetch changes.
However, from your command prompt output, the error appears to be happening during a
fetch rather than a
clone, so it’s quite possible that it will appear again.
Often, network timeout errors such as this are dealt with by increasing the
http.postBuffer setting for git. e.g.
git config --global http.postBuffer 524288000
See The remote end hung up unexpectedly while git cloning (StackOverflow) for more details on using this setting.
Of course, you should also ensure that you are running the latest version of Git For Windows.
If this doesn’t work, then it is recommended to switch your repository URL from HTTP to SSH. See Git over SSH for instructions on setting up SSH keys.
