You’re chatting with ChatGPT, and suddenly, the message pops up: “Network connection lost. Attempting to reconnect…” The chat freezes, your words hang mid-air, and you’re left staring at a blank screen. This error stops ChatGPT from sending or receiving data, interrupting your session. The problem sounds scary, but it’s usually simple to fix. In this guide, you’ll learn what this error means, why it happens, how to fix it step by step, and how to keep it from coming back.
What Is “Network Connection Lost. Attempting to Reconnect…” in ChatGPT?

When you see this message, it means ChatGPT temporarily lost contact with OpenAI’s servers. ChatGPT depends on a live internet connection to send and receive text through a system called a WebSocket. This connection allows messages to flow in real time. If your network drops, if OpenAI’s servers take too long to respond, or if your browser can’t reach the service, the app stops the chat and tries to reconnect automatically.
You’ll often see this message at the bottom of the ChatGPT window or in a small banner across your screen. On the web version, it may appear after you press “Enter” or when ChatGPT is in the middle of typing. On mobile, the chat might freeze or display a short notice that says “Reconnecting…” before it resumes. The issue isn’t usually permanent, but it signals a broken bridge between your device and OpenAI’s system.
Common Causes of “Network Connection Lost” in ChatGPT
Several things can trigger this problem. Some come from your side, others from the server.
- Weak or unstable Wi-Fi signal interrupts data flow between your device and OpenAI’s servers.
- VPNs or proxy settings block WebSocket connections that ChatGPT uses to communicate.
- Browser cache or cookies store outdated data that interferes with new sessions.
- Temporary OpenAI service issues or scheduled maintenance affect all users.
- Firewalls or antivirus tools mistakenly block ChatGPT’s data exchange process.
- High network latency or low bandwidth causes slow responses or timeouts.
- Outdated browser or network drivers break compatibility with ChatGPT’s system.
How to Fix “Network Connection Lost. Attempting to Reconnect…” in ChatGPT?
These fixes address both local network issues and system settings that can cause ChatGPT to lose contact with OpenAI’s servers. Each fix explains why it’s linked to the error, what happens once it’s solved, and what you can do to apply it.
Fix #1: Restart Your Internet Connection
This error is often caused by unstable or weak internet signals. Restarting your router or modem refreshes your network connection, assigns a new IP address, and clears temporary routing conflicts. Once your internet stabilizes, ChatGPT reconnects to OpenAI’s servers and messages begin streaming normally again.
Here are the steps you can follow to restart your connection:
- Turn off your Wi-Fi router or modem.
- Wait about 30 seconds.
- Turn it back on and wait for all lights to turn green or stable.
- Reconnect your device to Wi-Fi or Ethernet.
- Reload ChatGPT and check if the error disappears.
Fix #2: Clear Browser Cache and Cookies
Old browser data sometimes interferes with ChatGPT’s real-time communication. Cache and cookies can hold expired login tokens or outdated scripts, which block WebSocket requests. Clearing them helps ChatGPT load a fresh session from OpenAI’s servers. Once cleaned, the app should reconnect smoothly and respond faster.
To do this properly, follow these simple steps:
- Open your browser settings.
- Select Privacy and Security.
- Click Clear browsing data.
- Select Cache and Cookies, then confirm.
- Restart the browser and try ChatGPT again.
Fix #3: Disable VPN or Proxy
VPNs and proxies can block or slow ChatGPT’s connection by rerouting traffic through different servers. This often interrupts secure WebSocket channels that OpenAI uses. Disabling your VPN gives ChatGPT a direct path to the servers. Once disabled, ChatGPT usually reconnects instantly and performs without lag.
Just turn off your VPN or proxy for a few minutes and reload the ChatGPT page. If the chat resumes, whitelist ChatGPT in your VPN settings or use a stable network without tunneling tools.
Fix #4: Check OpenAI’s Server Status
Sometimes, the problem isn’t from your device at all. OpenAI’s servers may be undergoing maintenance or facing temporary downtime. When that happens, ChatGPT can’t maintain a live connection. Once the servers stabilize, your chat window reconnects automatically and messages resume.
You can confirm this by visiting status.openai.com. If the site shows “outage” or “degraded performance,” wait until the indicator changes to “operational.”
Fix #5: Reset Network Adapter (Windows)
Misconfigured or corrupted network adapters can block internet requests or cause packet loss. Resetting your adapter rebuilds all network settings and clears driver conflicts. After the reset, ChatGPT reconnects smoothly because your device starts with clean networking parameters.
Here are the steps you can follow to reset the adapter:
- Press Windows + I to open Settings.
- Go to Network & Internet.
- Click Advanced network settings.
- Select Network reset and confirm.
- Restart your PC, then open ChatGPT again.
Fix #6: Turn Off Firewall or Antivirus Temporarily
A strict firewall or antivirus may mistake ChatGPT’s live connection as suspicious traffic and block it. Turning them off briefly helps test if that’s the cause. When the protection is off and ChatGPT reconnects normally, you’ll know the security app was the problem.
Open your firewall or antivirus control panel, disable it temporarily, and test ChatGPT. If the issue disappears, add OpenAI or ChatGPT to the safe list and re-enable your protection.
Fix #7: Update Your Browser or ChatGPT App
This issue can occur if your browser or app uses outdated connection protocols. Updating installs new security and WebSocket compatibility patches. After updating, ChatGPT maintains a stable and secure connection without frequent reconnects.
Simply update your browser (Chrome, Edge, Safari, Firefox) or ChatGPT desktop/mobile app to the latest version, then reopen ChatGPT.
Fix #8: Flush DNS Cache
A corrupted DNS cache can point your system to the wrong OpenAI server location, breaking the link. Flushing it clears old records and forces your device to fetch new server IPs. Once cleared, ChatGPT can locate the correct domain and reconnect instantly.
Here’s how to do it on Windows:
- Press Windows + R, type cmd, and hit Enter.
- Type ipconfig /flushdns and press Enter.
- Wait for the message “Successfully flushed the DNS Resolver Cache.”
- Close the Command Prompt and reload ChatGPT.
Fix #9: Try Another Browser or Device
Sometimes, the browser or device itself is the problem. Extensions, corrupted profiles, or OS-level network restrictions can block ChatGPT’s connection. Trying another browser or switching to mobile helps isolate the cause. If ChatGPT connects fine elsewhere, the issue is local to your original setup.
Open ChatGPT on a different browser or another device. If it reconnects normally, reinstall or reset the first browser to remove broken settings.
Prevention Tips to Avoid Errors in ChatGPT
A few simple habits can stop this issue from showing up again.
- Keep your browser and system updated.
- Use a wired internet connection for stability.
- Restart your router weekly to refresh its IP session.
- Don’t overload your connection with too many downloads while chatting.
- Avoid unreliable VPNs or proxies.
- Use trusted antivirus programs and update them regularly.
- Check OpenAI’s status page before assuming the problem is yours.
Conclusion
The “Network connection lost. Attempting to reconnect…” message means ChatGPT lost its link to OpenAI’s servers. It’s not a serious error. Usually, weak Wi-Fi, cached data, or short server issues are behind it.
Apply the fixes one by one, and your chat should return to normal. If you’ve tried everything and the problem continues, contact OpenAI Support or check their official channels for updates. A stable connection is the key to keeping your AI chat smooth and fast.
