Why Your Instagram Post Isn’t Posting — and How to Fix It
If you’ve been asking yourself “Why isn’t my Instagram post posting?”, you’re certainly not the only one. Many Instagram users encounter this issue at some point — from photos that get stuck uploading, to videos that error out mid-way, to reels that never appear on the feed. This guide will walk you through the most common reasons for posting failures and give you actionable solutions so you can quickly get back to sharing content with your audience.

Check Your Internet Connection (Wi‑Fi or Mobile Data)
A weak or unstable connection is one of the top causes of failed Instagram uploads. Even if your device shows you’re connected, the bandwidth may be insufficient to handle large files.
Steps to Diagnose and Fix:
- Switch between Wi‑Fi and mobile data to see which works better.
- Run a connection speed test via services like Speedtest.net.
- Move closer to your Wi‑Fi router, or restart it.
- If on mobile data, check if your carrier is throttling speeds.

Verify Instagram’s Server Status
Sometimes the fault lies with Instagram’s servers themselves.
How to Check:
- Visit Downdetector.com for outage reports.
- Check Instagram’s official Twitter/X feed.
- Search “Instagram down” on Google News for real‑time coverage.
If Instagram is down, the only fix is to wait until it’s resolved.

Clear Instagram’s Cache and Storage
Corrupted cache can slow performance and interrupt uploads.
Android:
- Go to Settings → Apps → Instagram.
- Tap Storage & Cache.
- Select Clear Cache and, if needed, Clear Storage (this logs you out).
iOS:
- Use Settings → General → iPhone Storage → Instagram → Offload App.
- Reinstall from the App Store.

Confirm File Size and Format Compliance
Instagram enforces strict requirements on uploads.
Post Type | Max File Size | Supported Formats |
---|---|---|
Photo | 30 MB | JPEG, PNG |
Video | 650 MB (up to 60s) | MP4, MOV |
Reel | 4 GB (up to 90s) | MP4 |
Tips:
- Resize images before uploading.
- Convert video to MP4 H.264 for compatibility.
- Keep aspect ratios in the 1.91:1 to 4:5 range for feed.

Review Instagram’s Community Guidelines
Some uploads fail because the content breaches Instagram policies.
Common Violations:
- Nudity or sexual imagery.
- Copyrighted media without rights.
- Hate speech or harassment.
- Explicit or violent imagery.
Review Instagram’s Community Guidelines before posting to avoid rejections.

Investigate Account Restrictions or Shadowbans
Persistent issues may be account‑related.
Possible Causes:

How to Resolve:
- Check notifications in the app.
- Slow down your activity for a few days.
