VSCode: Remote - SSH extension - nothing happens when trying to conncet to remote server - visual-studio-code

I have recently discovered vscode and the remote development extension, and wanting to try it out, but I can't get the damn thing to connect to my development server.
I've installed the both the vscode and vscode insiders packages by downloading the .deb packages manually on my local machine and installed the extension it self by executing this line:
ext install ms-vscode-remote.vscode-remote-extensionpack
Afterwards my pre-configured ssh hosts gets discovered fine and i have key-based auth running and it works fine when connecting to the server from a terminal.
But when I try to connect to the server, by right clicking and selecting one of the two options, only a notification saying "Confirming hostname is reachable" pops up for a second or two and then nothing else happens.
There are no information in the "output" view, other than this line:
remote-ssh#0.42.2
I've checked and confirmed the remote server has the needed prerequisites.
Also i see nothing in the /var/log/audit/audit.log on the remote server when trying to connect, so I dont even think it tries to establish a connection.
What am I missing ?
Local OS: Linux Mint 19 Tara
Remote OS: CentOS 7

I found the issue - "+" signs makes the extension fail: https://github.com/microsoft/vscode-remote-release/issues/612
I have this line in my local .ssh/config
Host *+*
ProxyCommand ssh $(echo %h | sed 's/+[^+]*$//;s/\([^+%%]*\)%%\([^+]*\)$/\2 -l \1/;s/:/ -p /') nc -q0 $(echo %h | sed 's/^.*+//;/:/!s/$/ %p/;s/:/ /')
Which allows me to connect to host b through host a like so:
ssh hosta+hostb
Removing that fixed the issue, and I connect succesfully to a remote host - it simple seems that that vscode dislikes that line.

VS Code Remote-SSH won't reconnect to one specific working directory on remote Ubuntu host

I'm using VSCode 1.72.2 with Remote-SSH v0.90.1 on Windows to develop against an AWS EC2 VM running Ubuntu 22.04 LTS. A couple days ago, I was working in my project source folder in /opt/t4/ on the target host. When I was finished, I stopped the VM from the AWS console, forgetting that VS Code was still SSHed in.
When I brought the VM back up, I can reconnect VS Code/Remote-SSH to the host as before, except that I can no longer connect using /opt/t4/ as my working directory. I can use any directory except the one I was using when I disconnected.
I can navigate down to it and work in it if I use /opt/ as my working directory. I can navigate to it by manually SSHing to the remote host. I can create a subfolder in a remote shell at /opt/t4/test/, and then connect VS Code using that subfolder as my working directory. I can see and select /opt/t4/ in the Open Folder dialog in VS Code. But when I try to connect using that working directory, the connection times out with a not-particularly-useful error message:
[00:05:49.867] SSH Resolver called for "ssh-remote+my.remote.host", attempt 2, (Reconnection)

I tried Remote-SSH: Uninstall VS Code Server from Host from VS Code.
I tried deleting ~/.vscode-server on the Linux host from an SSH session.
I tried Remote-SSH: Kill VS Code Server on Host from VS Code.
I tried Remote-SSH: Kill Local Connection Server for Host from VS Code.
I tried deleting and recreating the host connection details in the local config file from SSH-Remote.
I tried rebooting both local and target hosts.
I tried setting /opt/ as my working dir, then deleting and recreating /opt/t4. I was able to do this, but as soon as I try reconnecting using /opt/t4 as the working dir, VS Code still fails to connect.
I'm... stumped. My suspicion is that there is something corrupt cached Windows-side, but I don't know where to look for that.
Microsoft is aware and working on a fix. There are a variety of workarounds in this thread: https://github.com/microsoft/vscode-remote-release/issues/7324
Thanks to the link from #Mike Barry, I managed to find the local workspace for that target folder and delete it to force it to reinitialize, which cleared the issue.
Deleted C:\Users\me\AppData\Roaming\Code\User\workspaceStorage\[guid]\ and reconnected with no problem.

vscode remote ssh connection cannot connect on windows server 2022

I'm trying to setup Remote SSH extension on vscode to connect to a server that runs Windows Server 2022.
First, I can connect with SSH from the terminal ssh username#public_ip -p port then I enter the password and I can access the server.
I installed the Remote - SSH extension on vscode. I was able to connect to a Raspberry Pi without problems... But I cannot connect to a Windows Server 2022.
It asks me to enter the username password twice, then after a few seconds it stops with two errors pop-ups (see picture below).
Could not fetch remote environment
Failed to connect to the remote extension host server (Error: WebSocket close with status code 1006)
errors
Also, from another machine. I can connect to my server with vscode and the same extension (Windows Server 2022) without any problems so I don't think that the server has any issues. Seems like the problem is on my computer that won't connect.
I was able to connect once but I did break something and I don't know what. I tried to reinstall the extension but nothing helped.
EDIT:
I think I fixed it.
Here's what I did.
I uninstalled the Remote - SSH extension
I opened the settings.json on my local computer and deleted everything that had to do with this extension.
Deleted the config file from C:\Users\username\.ssh\config
I restarted vscode
Installed the extension
And it worked.

VS Code Remote SSH Connection not working

Im trying to setup vscode with the remote developement extensions on a second pc. While it works on my main one it doesnt on the second one. Tried reinstalling vscode, extensions and using older versions but nothing works.
When trying to connect it cancels after chosing the os. So I cant even type in the password.
I set it up in the exact same way as with the other pc.
Any ideas?

Depending on the system you are in, when you first try to connect, a vscode-server will be set up and configured on your server.
In linux that can be in /Home/<user>/.vscode-server
If you are on windows, check what that is.
The first solution is to try the extension command: Remote-SSH: kill VS Code Server on Host
Open the command pallet (CTRL + SHIFT + P or COMMAND + SHIFT + P (mac) ).
And type Remote kill :
Then try to connect again! (That will kill the server on the host! Which will make it start again on the next try)
If that doesn't work, and things are still failing:
Delete, rm
Then a good solution that can work is: to connect to your server through terminal (vscode terminal, gnome-terminal, whatever). Then go and remove /Home/<user>/.vscode-server
Try to connect after that. At the attempt the server will be re-installed completely anew, chances are it will work. (I did that and it worked for me, so whatever that was going wrong on the vscode-server: just start all over)
But again: you will lose things, config, meta data, etc. (because you start anew).
Update:
As stated by #natevw in the comments:
I found that removing only the .vscode-server/bin subfolder helped straighten things out and afaict kept my data/settings.
Removing only vscode-server/bin seems to work well, and the config, metadata, etc. remains untouched.
I downgrade Remote-SSH plugin to 0.51.0, rm -rf $HOME/.vscode-server on the remote machine. Connect again, VSCode will download and install a new .vscode-server. Then upgrade Remote-SSH plugin, everything works.
One way worked for me is, by adding this line in the vscode settings (JSON) file.
"remote.SSH.useLocalServer": false
I met the same problem. After I did these steps, it works:
on the remote server:
rm -rf ~/.vscode-server
rm -rf ~/.vscode
On the local VS code:
reinstall remote-ssh
In case all the above fails, here's how I fixed my issue.
First, I was able to SSH into my remote server (Ubuntu 22.04, Raspberry Pi 4, arm64) using a simple bash terminal. So I logged in using my terminal (macOS), and I went to
cd $HOME/.vscode-server/bin/WHATEVER-HASH-YOU-HAVE/
In this directory, there is a file named server.sh. I tried running this script, and I got the following error:
./node: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory
The issue was clear: there was a missing shared library on my system. Either Node.js now requires that or the new version of the SSH-Remote extension; I don't know. I did not spent the time to dig into those specifics.
But to fix that, I simply did:
sudo apt-get install libatomic1
That installed the missing shared library.
After that, I delete $HOME/.vscode-server:
rm -rf $HOME/.vscode-server
and tried again connecting using VSCode. It worked!
Hope this can help someone like me, for whom all other options failed.
Issue: while trying to ssh connect to Linux(remote machine) using vscode.
Solution: remove/delete the bin folder inside .vscode-server and then reconnect to the remote machine
In remote server:
remote_name:~$ rm -rf ~/.vscode-server/bin
*reconnect to remote machine*
It turns out that my fish was a obstacle for vscode server.
Then I tried
chsh -s /bin/bash
And works fine.
I worked adding \\ in the path of the .config
I share the steps
Go to .config settings
select configuration
add double \\
Just deleted old host information from ssh settings file and problem solved.
I had faced this issue when I tried to connect to a Linux server from a windows laptop.
It was using the wrong fingerprint.
It worked for me after removing the line related to that server from $HOME/.ssh/known_hosts
I ran into the same issue, it got fixed when I updated the path of the IdentityFile from 'ssh_key' to '~/.ssh/ssh_key' (the entire path I mean) so that the VS code could recognize it.
Restart remote machine worked for me (after trying all the previous answers with no luck).
Giving you the oldest trick of the book:
restart
It worked for me and I laughed hysterically for exactly 57 seconds. Happy reconnecting to the server my dear Coder!
I could not connect to the server, my issue was the remote server was full
check with the command df -h if the disk is full !
Here is an alternative for Remote SSH, pls check my answer at: https://stackoverflow.com/a/68046111/13089935
TLDR:
We can use a web-based VS Code that is installed on the server directly.

Remote editing over ssh to windows server

Remote SSH plugin states VS Code Insiders has experimental support for Windows 10/Server 1803+ using the official OpenSSH server.
I have the official OpenSSH server installed and configured on Windows Server 2019 1809. I can connect via pubkey authentication and have PowerShell Core over ssh working as well. I tried both Remote SSH and Remote SSH nightly plugin. At first it was complaining that it couldn't find bash. So I installed git bash and added it to the system path. I get the following error when attempting to connect to my windows server:

Anybody know the magic sauce to get Remote SSH working w/ Windows 10/Server?
Looks like VSCode is attempting to run bash on the server which I'm guessing would resolve to git's bash which is mingw based as I recall. VSCode should be running Powershell on the server.
Did you include your server in the list of windows remotes in the extension's settings?
Requires "remote.SSH.windowsRemotes" setting. Here is the documentation.
"remote.SSH.windowsRemotes": ["myserver"]

Failed to parse remote port from server output: bash: no job control in this shell

I am trying to use VSCode - Insiders to run code on a docker container in a remote AWS machine using the Remote - SSH plugin. I have opened a terminal and set up port forwarding like so: ssh -L 2201:localhost:2222 user#host -N -i ~/.ssh/id_rsa. Then in VSCode I try to connect to root#localhost and it starts up, but then gives me an error message:
> Found existing installation...
> Found running server...
>
> bash: no job control in this shell
"install" terminal command done
Received install output: bash: no job control in this shell
Failed to parse remote port from server output: bash: no job control in this shell
I started doing this process a couple days ago and it worked. Yesterday it was in and out a bit, and today it's not working at all. I've tried turning it off and on again, but can't get it to work. In case it's relevant, I am on MacOS with the Mojave OS.
Edit:
Magically, it worked today (the following day) the first time. I would still be interested in knowing how to fix this next time it breaks. In case this helps, here's the output from when it is working:
SSH Resolver called for "ssh-remote+7b22686..."

Edit 2: And now (the following following day) it's not working again.
Edit 3: I have a config file at ~/config. Here are the contents:
Host *
User root
Port 2201
IdentityFile ~/id_rsa
In the specific implementation shown above, you have User root in your config and are logging in with root#localhost, so you have your username twice. Leave the config file as is and just enter localhost in VSCode. This still doesn't solve the instability issue, but it does fix one problem.
I have the same issue when configuring my server. It solved by this issue. After save your config file for remote server, change the remote shell path like this issue, and then connect, you will in.
