Hey @Kyle_Nguyen @glomar_dev,
I’m seeing the OP had a similar situation. DNS was slow, and streaming connections were dropping with ECONNRESET. You might have the same root cause, or it might be something else, so we should narrow it down.
Try these first:
-
Disable HTTP/2: Cursor Settings > General, search for “HTTP/2”, enable “Disable HTTP/2”, then fully restart Cursor. In a similar thread this helped some users.
-
Network Diagnostics: Cursor Settings > Network > Run Diagnostics, then paste the results here.
-
Mobile hotspot test: Connect via mobile data. If it works there, the issue is likely your network.
@Kyle_Nguyen I see both Windows and Amazon Linux in your info. Are you using SSH Remote? If yes, that’s important context.
@glomar_dev The fact it worked for an hour and then failed could point to something at the network level killing long lived connections. Are you using a VPN, proxy, or a corporate network?
Let me know what you find, especially the network diagnostics output.
