Ssh no longer connects to remote host

[Joseph_Noonan]

Describe the Bug

I have an Ubuntu 16.04 host that I was using SSH to connect to for remote development. I had to disconnect it to work on something else, and when I reconnected it, it no longer establishes a connection. I enter the password multiple times, but it still says “Failed to connect to the remote extension host server.” I can SSH into the device from a terminal window with no issues. How do I fix this? I get prompted multiple times for the password, which I enter correctly, but it still will not connect.

Steps to Reproduce

I am not sure how to reproduce this. It was working fine until I unplugged the remote host. I did verify that the IP address is the same, and I can SSH into the device from a regular terminal window.

Expected Behavior

Successfully connect to the remote device.

Does this stop you from using Cursor

Yes - Cursor is unusable

This error message displayed after I entered the password at least 5 times:

Failed to connect to the remote extension host server (Error: StatusError(StatusError { url: “https://cursor.blob.core.windows.net/remote-releases/faa03b17cce93e8a80b7d62d57f5eda6bb6ab9f0/vscode-reh-linux-alpine.tar.gz”, status_code: 404, body: “\u{feff}<?xml version=\"1.0\" encoding=\"utf-8\"?>BlobNotFoundThe specified blob does not exist.\nRequestId:49804102-101e-001f-2901-f0d0a0000000\nTime:2025-07-08T12:09:01.3360262Z” }))

Hi @Joseph_Noonan, could you try switching to the Anysphere Remote SSH extension?

[Joseph_Noonan]

@ravirahman I will give it a try and let you know.

@ravirahman That worked! Thanks!
