How To Fix “Our Systems Have Detected Unusual Activity From Your System Please Try Again Later” On ChatGPT?

To fix “Our systems have detected unusual activity from your system please try again later” on ChatGPT, you can check your internet connection, clear browser cache and cookies, and use a different browser or incognito mode. Additionally, you can check for malware, and disable VPN or proxy.
1. Check Your Internet Connection
A stable internet connection is essential for ChatGPT to function correctly.
If your connection is unstable or down, it may lead to the error message “Our systems have detected unusual activity from your system.”
Ensuring a stable connection can help you regain access to ChatGPT.
- Verify that your device is connected to the internet by checking the network icon in the system tray or menu bar.
- Try loading a webpage or use another online service to confirm your connection is working.
- If connected via Wi-Fi, check the Wi-Fi signal strength and move closer to the router if necessary.
- Restart your modem and router by unplugging them for about 30 seconds and then plugging them back in.
- If you’re using a wired connection, ensure the Ethernet cable is securely plugged in at both ends.
- Contact your internet service provider if you’re unable to resolve the connection issue on your own.
2. Clear Browser Cache And Cookies
Clearing your browser cache and cookies can resolve issues with corrupted or outdated files that might be causing the “Our systems have detected unusual activity” error on ChatGPT.
This action refreshes your browser’s memory and can help restore access to the service.
Google Chrome:
- Click three dots > “More tools” > “Clear browsing data.“
- Select “All time” and check “Cookies and other site data” and “Cached images and files.“

Mozilla Firefox:

3. Use A Different Browser Or Incognito Mode
Sometimes the issue might be isolated to the browser you are using.
Switching to a different browser or using incognito/private mode can bypass certain local settings that might trigger the detection system.
- Open a different web browser installed on your device.
- Alternatively, open a new incognito or private window in your current browser (usually found in the File menu or accessible by pressing Ctrl+Shift+N on Windows or Cmd+Shift+N on macOS).
- Try accessing ChatGPT again in the new browser or window.
4. Check For Malware
Malware on your system can cause unusual activity that might be detected by ChatGPT’s security systems.
Running a malware scan can detect and remove such malicious software.
- Install a reputable antivirus or anti-malware software if you don’t have one already.
- Update the software to ensure it has the latest virus definitions.
- Run a full system scan to detect any potential threats.
- Follow the software’s recommendations to deal with any detected malware.
- Restart your computer and try accessing ChatGPT again.
5. Disable VPN Or Proxy
If you’re using a VPN or proxy, it might be causing the “Our systems have detected unusual activity” error due to shared IP addresses or other factors that can appear suspicious to security systems.
- Turn off any VPN or proxy service you may be using.
- If applicable, disconnect from any corporate or school networks that use proxy servers.
- Connect directly to your home or a trusted network without any intermediaries.
- Attempt to access ChatGPT again to see if the issue is resolved.
