Why Is My IG Post Not Posting? Common Causes and Fixes
If you’ve found yourself asking "why is my IG post not posting" just when you’re eager to share that perfect picture or video, you’re definitely not alone. Instagram posting errors are common, and they can be both confusing and frustrating. In this detailed guide, we’ll explore the most frequent causes behind these issues and give you actionable troubleshooting steps to help get your content online quickly.

Check Your Internet Connection Strength
One of the most overlooked issues is a weak or unstable internet connection. Whether you’re on Wi-Fi or mobile data, Instagram depends on a strong and stable connection to upload your content successfully.
Steps to Verify Your Connection
- Switch between Wi-Fi and mobile data to see if the problem persists.
- Run an online speed test using tools like Speedtest.net.
- Restart your router or use Airplane mode to reset network connections.
Slow upload speeds can easily result in incomplete uploads that trigger posting errors.

Confirm Instagram Server Status
Sometimes, the problem is completely outside your control and lies with Instagram’s own systems.
How to Check
- Visit Downdetector to see current Instagram outage reports.
- Check Instagram’s official Twitter or Threads account for maintenance updates or downtime announcements.
When server issues are present, the only solution is to wait for Instagram to fix the problem.

---
Update the Instagram App
Using an outdated Instagram app can cause compatibility issues and posting failures.
Why Updates Matter
- Updates often patch security flaws.
- They maintain compatibility with new versions of mobile operating systems.
- Bug fixes can specifically address posting glitches.
Action
Open your device's app store (Google Play Store or Apple App Store), search for Instagram, and tap Update if a newer version is available.
---
Clear App Cache or Reinstall the App
A corrupted cache can prevent posts from uploading. Clearing your cache removes temporary files and data that may be interfering.
Android Example
Settings > Apps > Instagram > Storage > Clear Cache
iOS Action
On iOS, there’s no direct cache clear option—uninstall and reinstall Instagram instead.
This refreshes the app to its default state and may fix the posting error.
---
Review Post Content for Community Guidelines
Instagram enforces strict content policies. If your caption, hashtags, or image/video violate these guidelines, your post may fail.
Common Violations
- Nudity or explicit violence.
- Hate speech or discriminatory content.
- Spamming behavior or misleading promotions.
Check Instagram’s Community Guidelines to ensure your post complies before uploading.
---
Check Image/Video Format and Size Limits
Instagram accepts only specific media formats and sizes. Large video files or unsupported image ratios can trigger errors.
Content Type | Supported Formats | Max Size | Recommended Ratio |
---|---|---|---|
Photo | JPEG, PNG | 30 MB | 1.91:1 to 4:5 |
Video | MP4, MOV | 650 MB | 16:9 to 4:5 |
Compress or convert files to meet these specifications before posting.

Ensure You Haven’t Hit Daily Posting Limits
Instagram may impose rate limits to prevent spam-like behavior. While exact limits aren’t public, posting too much within a short period can lead to temporary blocks.
If you believe you’ve hit a limit, halt posting for at least 24 hours.
---
Log Out and Back Into Your Account
Session data can occasionally go stale. Logging out and back in refreshes your authentication details.
Steps:
- Tap your Instagram profile.
- Go to Settings > Log Out.
- Log back in using your account credentials.
---
Try Posting From Another Device or Browser
If your app fails to post, use Instagram Web from a desktop browser. This can help determine whether your device or the app is the problem.
---
Examine If Third-Party Apps or VPNs Are Interfering
VPN services or third-party apps interacting with Instagram may disrupt posting.
What to Do:
- Temporarily disable your VPN.
- Remove third-party apps connected to Instagram.
- Attempt posting without these services active.
---
Identify If Account Restrictions or Shadow Bans May Apply
Instagram can restrict accounts over policy violations, limiting posting capabilities.
Signs of Restriction:
- Decline in engagement or reach.
- Warning messages about violations.
- Loss of access to certain features.
Check your account status at Settings > Account > Account Status.
---
Troubleshoot Using Instagram Help Center Resources
Instagram’s Help Center contains official and updated instructions to solve posting issues. Search for:
- “Can’t upload photos”
- “Instagram won’t post”
These resources are regularly updated and tailored to app versions.
