This article shows how you can reset your git state to any older/previous commit and then push to your origin repository.
Reset to older commit
git reset --hard <commit-hash>
Example:
git reset --hard 39fdf70
Force push to origin repository
git push origin --force
# OR
git push --force
If you only want to reset in your origin repository and not in your local repository, then:
git push origin +<commit-hash>:<branch-name>
Example:
git push origin +39fdf70:master
where,
39fdf70 is the commit that you want your origin repo to reset to
+ is used for force push
