I had a project working with Git and encountered a phenomenon whereby running git pull returned the following message:

Already up to date.

My local branch content differs from the contents found in the remote.
For example,
A colleague committed changes to the remote branch, though these didn't happen in my local copy after the pull. I have the different history of the branch seen in my local repository from that seen on the actual remote repository, including lost commits.

Here’s what I’ve tried so far:

• Checked the branch I was working on with git branch.
• Checked the repository URL of the remote using git remote -v to match the actual repository.
• It compares the commit history with git log on my local and remote branches.

Here's what I suspect is going on:
My local branch is ahead of the remote branch. The remote might have changes that git pull doesn't pick up on.
