Summary
Bamboo executes a git ls-remote command while running a 'Source Code Checkout' task to query remote repositories for references without needing to clone or fetch the entire repository as part of updating source code to the latest revision.
This may sometimes fail due to connectivity issues to the repository server with an error like 'Failed to connect to localhost port 3128 after 1003 ms: Couldn't connect to server'.

3128 is the default port number where the HTTP/TCP proxy is used to listen both HTTP and HTTPS traffic.
And if it the proxy server is not running or a misconfigured HTTP_PROXY environment variable or facing some other issues it may not connect to repository.
Solution
Checking Proxy server status and restart
Check the proxy server status by running the command "
netsh winhttp show proxy" in Windows or "netstat -tuln | grep 3128" in Linux
Check HTTP_PROXY value and update
Check
HTTP_PROXYin environment variableCheck the git http-proxy settings by running the command
'git config --global --get http.proxy'are set correctly.
Unset the proxy setting if you are not planning to use proxy.
Remove the environment variable by running '
set HTTP_PROXY=' in Windows or 'unset HTTP_PROXY' in LinuxFor git run the command:
git config --global --unset http.proxy
