Vscode-remote-release: Fail connecting to remote server with time limit reach error using Remote - SSH

[shikiponn]

Hi VS code team,

I've started to use VS code again these days and bumped into a weired behaviour.

Problem:
If I try to ssh using Remote - SSH extension it gives me an error saying,

• Could not fetch remote environment
• Failed to connect to the remote extension host server (Error: Time limit reached)

while I can still ssh using zsh.
Is this a bug or just my settings matter?

Env:

• VSCode Version: 1.50.1
• Local OS Version: OS X 10.15.7
• Remote OS Version:Ubuntu 20.04.1 LTS
• Remote Extension/Connection Type: SSH
• Remote - SSH: 0.55.0

Steps to Reproduce:

1. Set up ssh config as
   Host host_on_google_compute_engine HostName XX.XX.XX.XX User my_user_name IdentityFile ~/.ssh/my_key IdentitiesOnly yes

2. Connect using Remote - SSH by selecting host_on_google_compute_engine from SSH TARGET pane in VS code.

3. Gives me an error as below and can't access to the remote
   

4. However just doing ssh host_on_google_compute_engine works

What I have tried:

• Deleting .vscode-server on remote and reconnect.

Thanks!

[muk-ai]

same here.
1.50.1 seems to be broken.
It works correctly with 1.49.3.

[shikiponn]

@muk-ai
Hi!
Following your solution, I've just downgraded my VS Code to 1.49.3 but still doesn't work.
Can you share me which Remote-SSH version you are using?

[muk-ai]

A day has passed and now I try again with 1.50.1, it doesn't cause any problems.
I have no idea why the problem has been resolved.

My environment is below.
vscode

1. open vscode 1.49.3
2. close vscode 1.49.3

I have confirmed that the following process remains on the remote server.

ec2-user 31855  1.5  3.1 971364 63472 ?        Sl   22:56   0:01 /home/ec2-user/.vscode-server/bin/2af051012b66169dde0c4dfae3f5ef48f787ff69/node /home/ec2-user/.vscode-server/bin/2af051012b66169dde0c4dfae3f5ef48f787ff69/out/vs/server/main.js --host=127.0.0.1 --enable-remote-auto-shutdown --port=0

after that

1. open vscode 1.50.1
2. close vscode 1.50.1

ec2-user 31855  0.8  3.1 971364 63472 ?        Sl   22:56   0:01 /home/ec2-user/.vscode-server/bin/2af051012b66169dde0c4dfae3f5ef48f787ff69/node /home/ec2-user/.vscode-server/bin/2af051012b66169dde0c4dfae3f5ef48f787ff69/out/vs/server/main.js --host=127.0.0.1 --enable-remote-auto-shutdown --port=0

I have confirmed there were two processes remain.
My guess is that having two versions of the process in existence is not a good thing.
There should be a conflict.

@shikiponn
Wouldn't it solve the problem to try to kill the node process?

[roblourens]

Are there any errors in the developer tools? Help > Toggle Developer Tools

[muk-ai]

@roblourens
The issue is no longer reproducing. Thank you for checking this issue.
But is it okay if the previous version of the process remains on the remote server when I update the vscode version?

[shikiponn]

@muk-ai
Thanks, but sadly I have no node process running

Checking my Dev Tools Console I see logs below.

[roblourens]

Sorry @shikiponn there must be something with your network setup or remote environment preventing us from opening a websocket connection to the remote server, even though it apparently started up successfully. I'm not sure what that would be or what else to ask.

[alhabarneh]

I've started getting the same issue since I updated my vscode, I connect remote ssh through sublime and webstorm to my server with no issues at all. So I decided to rollback to an older version of vscode! I rolledback to Oct 2020 1.51 and now it works just fine!
The version with issues is Nov 2020 1.52
The errors I have been having are:

• Could not fetch remote environment
• Failed to connect to the remote extension host server (Error: Time limit reached)

[roblourens]

Please file an issue and tell me the OS/version/architecture of your remote @alhabarneh

@roblourens Thanks for replying, my remote OS version is Linux x64 2.6.32-754.el6.x86_64 and I have just filed an issue
