This error occurs when you lack access to the repository or if the URL is incorrect. Check the repository link and your access permissions.

The 'Repository not found' error when cloning or pushing often points to incorrect repository URLs or lack of access permissions. First, verify the URL by ensuring you’re using the correct protocol (HTTPS or SSH) and that there are no typos. GitHub displays the correct clone URL on the repository’s homepage, so copying it directly helps prevent mistakes. If using SSH, ensure that your SSH key is added to GitHub. If permissions are restricted, request access from the repository owner. If the repository was recently renamed or deleted, confirm the new name or access a backup. Always double-check that your GitHub account or organization permissions align with the repository’s settings for seamless access.
