I See "Connection Lost. Please Check Your Internet and Try Again." in Agent Chat
Last updated: April 14, 2026
This message means your browser lost its real-time connection to the Gumloop server while your agent was responding. In most cases, refreshing the page will reconnect you and resume the conversation where it left off.
Symptoms
You see
Connection lost. Please check your internet and try again.in the chat window while the agent is mid-response.The agent's reply stops appearing — the loading indicator may freeze or disappear.
You cannot send new messages in the same chat until you refresh.
Cause
Gumloop uses a WebSocket connection to stream your agent's responses in real time. When that connection drops — due to an unstable network, your browser tab being backgrounded for too long, a VPN reconnecting, or a brief internet outage — the client detects the break and shows this error.
Behind the scenes, Gumloop tries to automatically reconnect up to four times with increasing delays. If all four attempts fail, you see the "Connection lost" message. The backend also keeps the agent's output stream alive for a short grace period (~30 seconds) so that a quick reconnect can pick up right where it left off without losing any text.
How to Fix It
Refresh the page. In most cases, this re-establishes the WebSocket connection and loads the full conversation history, including any text the agent generated while you were disconnected.
Check your internet connection. Make sure Wi-Fi or ethernet is stable. If you are on a VPN, try temporarily disconnecting it to rule out VPN-related drops.
Avoid backgrounding the tab for extended periods. Some browsers throttle or close WebSocket connections for inactive tabs. If you need to step away, keep the Gumloop tab visible or in its own window.
Start a new chat if the conversation won't resume. If refreshing does not restore the session, open a new chat with the same agent. Your previous conversation's generated files and artifacts are still accessible in your run history.
What Happens to My Agent in the Background?
When your connection drops, the agent may continue processing briefly on the backend while waiting for you to reconnect. If you reconnect within the grace period, the response picks up seamlessly. If you do not reconnect, the backend is designed to stop the agent's work after the grace period expires.
In rare cases — particularly with long-running tasks like file generation or large data processing — the backend may not stop the interaction immediately. If you suspect your agent continued running after a disconnect and consumed credits unexpectedly, check your credit usage and reach out to support@gumloop.com for help.
How to Reduce Disconnections
Use a stable network. Wired connections are more reliable than Wi-Fi for long agent sessions.
Break large tasks into smaller requests. Instead of asking your agent to process hundreds of items in one go, batch your requests. That way, if a connection drops, you lose less progress.
Keep the tab active. Browser power-saving features can close idle WebSocket connections. Keeping the Gumloop tab in the foreground helps maintain the connection.
