Connection Error using SSH

[Thomas_Li]

Where does the bug appear (feature/product)?

Describe the Bug

But if I am opening a remote project via SSH, agent chat shows Connection Error with Request ID: e00d2453-fbff-43af-9adc-bc72e31e77be

Steps to Reproduce

using SSH to connect to remote project and send anything in agent chat.

Hey, thanks for the report. Agent connection errors over SSH are a known issue we’re already tracking.

Please try the following steps:

1. Start a new chat:
   Sometimes the error gets stuck in a specific session, and starting a new Agent session can clear it.

2. Run Network Diagnostics:

   • Settings → Network → Run Diagnostic
   • Share the full output here

3. Check SSH connection logs and console errors:

   • Help → Toggle Developer Tools
   • Share any errors or warnings you see there
   • Open the “Output” panel: View → Output
   • In the dropdown, select “Remote-SSH”

4. Check MCP servers:
   If you have any MCP servers configured in Tools & MCP, temporarily disable them.

It would also be helpful if you could clarify:

1. Are you connecting via SSH to a Windows host or a Linux host?
2. Are you using any firewall or antivirus software?

Thanks for reply!

1. new chat won’t help. Connection error still shows.

2. Network Diagnostic seems fine, only Ping response took longer but it’s not blocking chat when I use chat without SSH.

3. error in developer console:

   DeveloperTools.txt (3.8 KB)
   RemoteSSH in output view doesn’t show error, setup is OK with server listening.

4. No MCP servers setup.

   I’m connecting SSH to from Windows to Windows. Firewall is Windows Firewall but 1 week ago it works fine.

Just now, with another hit in new chat, it runs through now… Monitoring if it is consistent.

unfortunately, very unstable, not working again.

Inspired by other user’s post, I found the issue can ONLY be gone when Output panel with “Remote-SSH“ selected. Other panel in display like “Terminal“ or “Debug Console“ instead of “Remote-SSH“ of Output will block chat agent. @deanrie

[HatriGt (AjeethKumar R)]

same here. new chat also gives same error.

[Choovy_Bi]

same here. just like @Thomas_Li said, with “Remote-SSH“ selected in the “Output“ panel, the agent will work.

I also am experience the same issue, where I must have the Output tab open to send agent requests. If I switch to the Terminal tab, it instantly stops working.

I also have this same issue, chat on remotessh session only work only works when the Output tab is open and selected.

Prior updates did not have this issue, and it was working fine until recently (after a recent update I assume).

Is there a fix for this besides keeping the Output tab open?

[symbolic-dev]

Downgrading cursor ide to 2.1.39 didnt resolve the issue directly, however downgrading Remote-SSH to version 1.0.17 after that did resolve the issue.

So maybe its just the remote-ssh version… keeping this config for now.
