Agent Mode Not Working from yesterday

Esmail_Md · September 11, 2026, 6:39am

I have been unable to use Agent Mode since yesterday.

Whenever I send a request in Agent Mode, the agent does not proceed and remains stuck under the chat box with the following statuses:

Planning next moves
Taking longer than expected…
Reconnecting

After waiting for a long time, I eventually receive the following error:

Internal Error
An unexpected error occurred on our servers. Please try again or contact support if the issue persists.

Request ID: 94c0240c-1d20-4528-9b4a-c3aa73153cce

I have already tried:

Switching to different Agents/models.
Starting a completely new chat/conversation.
Retrying the requests multiple times.

However, I experience exactly the same issue every time.

I noticed this occurred at approximately Sep 10, 08:20 PM (server time).

Hey @Esmail_Md, @EV_GEN - thanks for the reports and Request IDs!

Your requests are reaching us and the model is replying, but the response stream isn’t making it back to your machine, so you get the endless “Planning next moves / Reconnecting” and then that error. That’s almost always a VPN, antivirus/“web protection”, proxy, or ISP holding back the streaming connection, not your setup.

Try in order:

Cursor Settings > Network > HTTP Compatibility Mode → HTTP/1.1, fully quit and reopen Cursor, then send a quick “hello” in a new Agent chat.
Still stuck? Set it to HTTP/1.0 (long-polling), quit/reopen, try again.
Still stuck? Temporarily disable any VPN/proxy/antivirus web protection, or try a phone hotspot.

If none of those work, run Cursor Settings > Network > Run Diagnostics and paste the output plus a fresh Request ID, and I’ll dig deeper. Network troubleshooting

EV_GEN · September 11, 2026, 10:31am

Changing from HTTP/2 to HTTP/1.1 solved the problem. Thank you!

Same here after update. Took me a while to fight with it.
