Common Error Messages and Possible Causes
When Instagram fails to upload a post, you may see:
- “Couldn’t upload. Try again.”
- “Upload failed.”
- A spinning loader that times out without posting
Most common causes include:
- Poor network connection: Weak Wi-Fi or unstable mobile data.
- Unsupported file formats: Instagram supports JPEG/PNG for images and MP4 (H.264, AAC) for videos.
- File size too large: Large videos may exceed the upload limit.
- Cache/data corruption: Stored app data might block normal operations.
- Account restrictions: Temporary bans due to violating community guidelines.
- App bugs: Older app versions with unresolved issues.

Step 1: Check Instagram Server Status
Sometimes the problem is not on your end at all. Instagram’s servers could be experiencing downtime or outages.
How to check:
- Visit status tracking sites like Downdetector.
- Check Meta’s official platforms or support channels.
- Search on Twitter/X for trending outage reports.

If others are posting about the same upload issue, waiting until Instagram resolves the problem might be the only action needed.

Step 2: Verify Your Internet Connection
Uploads require a reliable and fast connection.
- Test both Wi-Fi and Mobile Data:
- Switch between them to see if uploading works better.
- Restart your router if on Wi-Fi.
- Run a speed test and aim for at least 5 Mbps upload speed.
---
Step 3: Update the Instagram App
Running outdated versions may lead to compatibility issues with Instagram’s servers.
On iOS:
- Open App Store → Updates → Update Instagram.
On Android:
- Open Google Play Store → Manage apps & device → Update Instagram.
---
Step 4: Clear Instagram Cache
Clearing cache removes temporary files and often fixes stalled upload problems.
On Android:
- Go to Settings → Apps → Instagram.
- Tap Storage → Clear Cache.
On iOS:
iOS doesn’t offer a direct cache clear. Instead:
- Offload the Instagram app:
- Settings → General → iPhone Storage → Instagram → Offload App.
- Reinstall from App Store (data saved in the cloud is preserved).
---
Step 5: Reduce File Size or Change File Format
Instagram has upload specs:
- Images: Up to 30 MB, 1.91:1 to 4:5 aspect ratio.
- Videos: Max 650MB for videos under 10 minutes (1080p recommended).
Tips:
- Resize images to around 1080px width.
- Compress videos using tools like HandBrake.
- Export using MP4 (H.264 codec) and AAC audio.

Step 6: Log Out and Log Back In
Session glitches can cause upload failures.
- Go to Profile → Settings → Log Out.
- Close the app and reopen.
- Log back into your account.
---
Step 7: Restart Device and Reset Network Settings
A quick restart often resolves temporary system conflicts.
If issues persist:
On iOS:
Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
On Android:
Settings → System → Reset Options → Reset Wi-Fi, mobile & Bluetooth.
---
Step 8: Disable Data Saver and Battery Optimization
Instagram’s data saver limits media upload quality and can stall uploads.
Data Saver Off:
- Open Instagram → Profile → Menu → Settings & Privacy → Data usage → Disable Data Saver.
Battery Optimization Off:
- Android:
- Settings → Battery → Battery Optimization → Instagram → Don’t optimize.
- iOS:
- Ensure Low Power Mode is off in Settings → Battery.
---
Step 9: Check Account Restrictions or Temporary Bans
Instagram may block uploads if your account violated guidelines.
Check in-App Notifications:
- Open Instagram → Inbox → Check for “Account Warning” messages.
If there’s a restriction, you’ll need to wait until the period ends.
---
Step 10: Reinstall Instagram (Backup Drafts First)
Reinstalling gives you a fresh app copy, but can delete drafts.
To save drafts:
- Publish them privately or save media to local storage before reinstalling.
Then uninstall Instagram from the device and reinstall from the app store.
---
Step 11: Contact Instagram Support
If previous steps fail, submit a problem report.
On Instagram:
- Profile → Menu → Settings & Privacy → Help → Report a problem.
- Select Include and Continue, describe the issue clearly.
- Attach screenshots or screen recordings.
