This error message indicates that the Git client was unable to connect to the remote repository on GitHub. The most likely cause is a network connectivity issue or a firewall blocking access to the server.
To resolve this issue, you can try the following steps:
- Check your internet connection and make sure you are able to access other websites.
- If you are behind a proxy or firewall, configure Git to use it by running the following command:
git config --global http.proxy <proxy-url>
- Try cloning the repository using SSH instead of HTTPS by running the following command:
git clone git@github.com:ltaoo/books.git
If none of these solutions work, there may be an issue with GitHub’s servers or your account permissions. In that case, you should contact GitHub support for further assistance.
