Could not establish connection to "localhost".

[juliussimonelli]

Issue Type: Bug

I had been using the same method to create an SSH connection between my docker container on AWS and VSCode using Remote - SSH (nightly) and it was working and recently it stopped working. I create a port forwarding ssh to a docker instance inside EC2 with something like this ssh -L 2201:localhost:2222 user@host -N -i ~/.ssh/id_rsa -v. user@host is an AWS instance running a docker container and I publish port 2222 when I create it the docker container, but I have to map port 2201 on the host to port 2222 in the container. Then I connect to it using a config file that looks like:

Host *
     User root
     Port 2201
     IdentityFile ~/id_rsa(base)

Then in VSCode I go to "Remote-SSH: Connect to Host" and enter localhost.

This had been working but now it doesn't. I get a message saying "Could not establish connection to "localhost"."

Here's the output from Remote - SSH:

This should be fixed now, I don't use that wget option anymore

Works again. Thank you!
