I asked @remote-ssh but it did not help

In step 2 of the troubleshooting wiki, what was the result of running the generated SSH command verbatim outside of VS Code?

I COULD successfully SSH to the remote machine with the generated SSH command

Pulse Secure VPN version:

Note:
After starting a VPN connection, the DNS Servers and Search Domains of current network will be changed. It could be a reason.

Does this repro with a very simple SSH configuration, say:

Host foo
  HostName 1.1.1.1
  User alice

If not, could you please share the minimal configuration that does repro?

@joshspicer Yes, you can use this minimal configuration to do repro. Though I think it doesn't matter what content are in SSH configuration files. I try different configurations, and the problem still exists.

Hi!
I have a similar issue. Also on my system the Remote Explorer is empty. However, I'm not using Pulse Secure VPN (or any VPN at all). Interestingly, the ssh connection to my machine works totally fine, I only cannot see or select my connection, but the Remote - SSH extension can connect to my machine just fine.

When I click the refresh button in Remote Explorer, I get this error:
Error running command remote-explorer.refresh: A system
error occurred (read ECONNRESET). This is likely caused by the
extension that contributes remote-explorer.refresh.

My configuration is similar to the one @joshspicer posted, just one host with HostName, User and IdentityFile.

Yesterday we observed the same behavior also on a machine of my colleague. But interestingly two other colleagues that have the same network setup don't have this problem, on their machines VSCode Remote works just fine.

What can we do to further diagnose the issue? We don't have an active VPN, but our IT department runs several network monitoring tools, perhaps one of those interferes with the extension.
