How to fix git push failed error is one of those searches every developer types in a slight panic, usually right after a deploy deadline. Your terminal spits out a red wall of text, the push hangs, and suddenly you’re not sure if it’s your fault, your network, or something bigger happening on GitHub’s end. Good news — most push failures are fixable in under five minutes once you know what to check.
Quick Summary:
- Git push failures usually stem from authentication issues, outdated local branches, permission errors, or large file limits.
- The error message itself almost always tells you the exact cause — read it carefully before Googling.
- Some push failures aren’t your fault at all; they trace back to a broader GitHub status page outage today affecting the platform.
- Fixing most push errors takes a few targeted commands, not a full repo reset.
- Knowing the difference between a local Git problem and a server-side outage saves you serious debugging time.
Here’s the thing — nine times out of ten, this is a config issue, not a Git conspiracy against you.
Why Git Push Fails in the First Place
Git push errors fall into a handful of buckets: authentication, sync conflicts, permissions, and file size limits. Rarely, it’s something outside your control entirely.
Understanding which bucket you’re in changes your fix completely. Throwing random commands at a permission error wastes time you don’t have.
The Most Common Git Push Error Messages
Each error message points to a specific root cause. Here’s the decoder ring.
| Error Message | Likely Cause | Quick Fix |
|---|---|---|
| “Updates were rejected because the remote contains work that you do not have locally” | Remote branch has newer commits | Run git pull --rebase then push again |
| “Permission denied (publickey)” | SSH key not added or expired | Regenerate and re-add your SSH key to GitHub |
| “remote: Support for password authentication was removed” | Using password instead of a token | Switch to a Personal Access Token or SSH |
| “File exceeds GitHub’s file size limit of 100MB” | Large binary or media file staged | Use Git LFS or remove the file from history |
| “fatal: unable to access… Could not resolve host” | Network issue or platform-wide outage | Check your connection, then check GitHub’s status page |
Notice that last row. Sometimes the fix isn’t on your machine at all — it’s a genuine GitHub status page outage today situation, and no amount of retrying will help until GitHub resolves it server-side.
Step-by-Step: How to Fix Git Push Failed Error
Work through this in order. Don’t skip to step 5 out of frustration.
- Read the exact error text. Git is verbose for a reason — it usually tells you precisely what broke.
- Confirm your authentication method. Run
git remote -vto check whether you’re using HTTPS or SSH, and make sure your token or key is current. - Pull before you push. Run
git pull --rebase origin mainto sync any commits you’re missing. - Resolve merge conflicts if they appear. Open the flagged files, fix the conflict markers, then commit and push again.
- Check file sizes. Anything over 100MB needs Git LFS — GitHub’s official large file storage documentation walks through setup.
- Verify repository permissions. Confirm you actually have write access to the branch you’re pushing to.
- Test your connection separately. Try
ping github.comor a simplegit fetchto isolate whether it’s your network or GitHub itself. - Check for a live GitHub status page outage today. If everyone on your team hits the same wall simultaneously, this is almost always the answer.
In my experience, step 3 fixes more push failures than any other single step. People forget how often teammates push commits between your last pull and your next push.
Common Mistakes & How to Fix Them
Developers repeat the same handful of mistakes when a push fails. Let’s clear them up.
Mistake #1: Force-pushing immediately.git push --force overwrites remote history and can wipe out a teammate’s work. Fix: use git push --force-with-lease instead — it checks for conflicts before overwriting anything.
Mistake #2: Assuming an expired token is a “GitHub problem.”
Personal Access Tokens expire on a schedule you set. Fix: regenerate the token in GitHub settings and update your credential manager.
Mistake #3: Ignoring the difference between local and server-side errors.
Rewriting your entire commit history won’t fix a genuine GitHub status page outage today. Fix: check githubstatus.com before touching your repo structure.
Mistake #4: Committing large binaries directly.
Video files, datasets, and design assets choke standard Git and trigger size-limit rejections. Fix: set up Git LFS from the start of a project, not after the error hits.
Mistake #5: Mixing SSH and HTTPS remotes.
Switching between the two without updating credentials causes repeated authentication failures. Fix: pick one protocol per repo and stick with it.

When the Problem Isn’t You — It’s GitHub
Here’s a scenario worth flagging. You’ve checked your token, your SSH key, your file sizes — everything looks clean, but the push still fails.
That’s your cue to check whether this is tied to a broader GitHub status page outage today, because platform-wide disruptions can block pushes, Actions, and webhooks simultaneously across thousands of repos.
Is it likely? Not usually. But when your entire team hits the identical error at the identical minute, coincidence stops being a reasonable explanation.
GitHub’s own documentation on troubleshooting connection errors is a solid first stop for distinguishing local misconfiguration from server-side trouble.
A Faster Way to Diagnose Push Failures
Think of a failed push like a stalled car. You wouldn’t immediately replace the engine — you’d check the gas gauge first.
Same logic applies here. Check the obvious, cheap things — auth, sync status, file size — before assuming something catastrophic broke.
Most push errors resolve with a pull, a rebase, or a fresh token. The dramatic fixes are rarely necessary.
Key Takeaways
- Most git push failures come from authentication problems, outdated branches, or file size limits.
- Reading the exact error message saves more time than guessing.
git pull --rebasefixes the majority of “remote contains work you don’t have” errors.- Force-pushing should always use
--force-with-lease, never a blind--force. - Large files need Git LFS, not a workaround commit.
- If your whole team hits the same error at once, check for a live GitHub status page outage today before touching your local repo.
- Git’s local-first design means your commit history stays safe even during a platform outage.
Push errors feel scarier than they actually are. Nine times out of ten, it’s a five-minute fix once you know which bucket the error falls into. Bookmark GitHub’s status page alongside your usual Git commands — that combo alone will cut your troubleshooting time in half.
FAQs
Why does my git push fail even though my code is fine?
Push failures are almost never about your code quality — they’re about sync state, authentication, or file limits. Run git pull --rebase first to rule out the most common cause.
CCan a GitHub status page outage today cause push failures for an entire team at once?
Yes. Platform-wide outages block push, pull, and Actions simultaneously across all affected repos, which is why simultaneous team-wide failures usually point to GitHub’s servers, not local misconfiguration.
Is force-pushing ever safe to fix a rejected push?
Only with --force-with-lease, which checks that no one else’s commits get overwritten. A plain --force push can silently destroy a teammate’s work.
