Quick answer: If Instagram stopped working on your PC after an update while connected to WiFi, clear the site data for Instagram, flush your DNS, and test the site in a fresh browser profile.
This problem is usually caused by a broken session, cached scripts from the update, or a WiFi-side DNS/filter issue that blocks Instagram from loading correctly.
Quick Fix Checklist
- Clear Instagram site data in your browser.
- Flush DNS and renew the network lease on the PC.
- Disable browser extensions that touch privacy, ads, or scripts.
- Test Instagram in a new browser profile with no sync data.
- Temporarily switch WiFi DNS to a public resolver.
Causes
| Cause | What it breaks | Fix |
|---|---|---|
| Corrupted Instagram site data after update | Login loops, blank feed, broken buttons | Clear cookies, cache, and local storage for Instagram |
| WiFi DNS filtering | Site loads partially or not at all | Change DNS and flush the local resolver cache |
| Extension conflict | Stories, reels, upload controls, or messages fail | Disable extensions and retest in a clean profile |
| Browser update mismatch | Instagram scripts fail after a browser or site update | Reset site permissions and hardware acceleration settings |
Step-by-Step Fix
1) Clear Instagram site data only
- Open your browser settings.
- Go to site data or cookies.
- Remove data for instagram.com and www.instagram.com only.
- Close all Instagram tabs and sign in again.
This is the fastest fix when the issue started right after an update.
2) Flush DNS on the PC
- Open Command Prompt as administrator.
- Run: ipconfig /flushdns
- Then run: ipconfig /release
- Then run: ipconfig /renew
If Instagram works on mobile data but not on your WiFi-connected PC, stale DNS is a common cause.
3) Change the WiFi DNS server
- Open your WiFi adapter settings.
- Set DNS manually to a trusted public resolver.
- Use a clean DNS path instead of the ISP default.
- Reconnect the browser and test Instagram again.
This helps when the WiFi network is resolving Instagram incorrectly after a router or ISP update.
4) Test in a new browser profile with extensions off
- Create a new browser profile.
- Do not sign in to sync yet.
- Open Instagram and test login, feed loading, and uploads.
- If it works, the problem is in your old profile or an extension.
Advanced fix: If Instagram still fails, disable hardware acceleration in the browser and clear the browser cache for the last 24 hours only. This can fix script rendering problems caused by a recent browser update.
Still Not Working
- Try a different browser on the same PC to isolate the issue.
- Check whether the WiFi network uses parental controls, ad blocking, or DNS filtering.
- Sign out of Instagram everywhere, then sign back in on the PC.
- Reset the browser permissions for pop-ups, cookies, and cross-site tracking for Instagram.
If Instagram works on another browser but not your main one, the issue is local to that browser profile, not the WiFi connection.
If the Problem Started After an Update
If the problem started right after an update, the timing strongly suggests a compatibility or local data issue.
Why this happens
Updates can change permissions, invalidate saved sessions, or leave behind temporary cached data that no longer matches the latest app or system version.
How to fix it
- Restart the device first to clear temporary glitches triggered by the update.
- Check whether a follow-up patch is already available for the app or system.
- Sign out and sign back in if the app still opens but a specific function fails.
- Clear cache or reinstall the app if the issue appears tied to corrupted local data.
- Look for reports from other users to confirm whether the update introduced a wider bug.
Important notes
- If many users report the same issue after the same update, a vendor-side patch may be required.
- Do not reset the whole device too early if simpler update-related fixes have not been tested yet.

FAQ
Why does Instagram only fail on my PC after an update?
Because the update can leave old site data, cached scripts, or extension rules that no longer match Instagram’s current code.
Why does Instagram work on my phone but not on my PC WiFi?
That usually points to a PC browser issue, DNS problem, or a WiFi filter affecting only the computer.
Will clearing cookies delete my Instagram account?
No. It only removes the saved login session and site data from the browser.
What if Instagram loads but messages or uploads fail?
Disable extensions first, then clear Instagram site data and retest in a clean browser profile.
Do I need to reset my router?
Only if changing DNS and flushing the PC cache do not fix the issue. Start with the PC-side steps first.
