I’m having trouble pushing my code to GitHub using SSH keys through the terminal on macOS. When I try to push my changes, I keep getting an error that says the hostname cannot be resolved.
The specific error message I see is:
ssh: Could not resolve hostname github.com:username/my-project.git: nodename nor servname provided, or not known
I tried following some solutions I found online but they didn’t work for my situation. It seems like there might be an issue with how I’m formatting the repository URL or maybe my SSH configuration isn’t set up correctly.
Has anyone encountered this type of hostname resolution error when working with GitHub SSH? I would really appreciate any suggestions on how to fix this connection problem.
This happens when your remote URL mixes SSH and HTTPS syntax. Looking at your error - github.com:username/my-project.git - you’ve got the hostname right but you’re missing the git@ prefix that SSH needs. I’ve seen this tons of times when people manually edit their .git/config file or copy URLs wrong. Fix the remote URL format first, then test your SSH connection separately with ssh -T [email protected] to make sure your SSH keys work with GitHub. If that command fails, it’s your SSH setup that’s broken, not the repo URL. Double-check that your SSH key is actually added to your GitHub account and your local SSH agent is running.
yeah, totally seems like a URL format issue. maybe u copied the clone URL wrong from GitHub - i’ve seen folks mix up HTTPS and SSH stuff. try running git remote get-url origin to check what your setup looks like.
I encountered a similar issue previously. It appears that the error message you’re seeing relates to the format of your repository URL. Ensure that you are using the correct SSH syntax, which should look like [email protected]:username/my-project.git. If your URL contains any mix of HTTPS syntax, such as https://, this will cause the aforementioned hostname error. You can verify your current remote URL by running git remote -v. If it does not match the SSH format, you should update it using git remote set-url origin [email protected]:username/my-project.git. This should resolve the hostname issue and allow your SSH connection to GitHub to work properly.
