In de log file on the remote host these entries are the last before the code server stops ..

Visual Studio Code Server .. v 1.76

I understand on 1 March the server code change and is now using the MAC address as a security....
On my remote server ( Strato VM ) there is no MAC address when I use IP LINK of IP ADDR.

Seems that the change introduced a new problem.

Using strato as well so that seems to be the problem,
are there any solutions to this yet?

Same problem. I can't find a solution yet

My vscode couldn't download the vscode-server remotely. It was just hanging. So, I logged into the remote machine and downloaded the vs-server manually:

wget  https://update.code.visualstudio.com/commit:92da9481c0904c6adfe372c12da3b7748d74bdcb/server-linux-x64/stable
mv stable vscode-server.tar.gz
tar -zxf vscode-server.tar.gz
mv vscode-server-linux-x64/* ./

Commit hash depends on your current version. You can check it in Help -> About.

Downgrade VSCode should fix it

[eleanorjboyd]

Could someone include their full remote-ssh logs?

@bvv400 could you elaborate a bit more on what you mean by this?

[bvv400]

@eleanorjboyd

This is de log file on de server when Remote SSH connection is started. Also the ifconfig.

92da9481c0904c6adfe372c12da3b7748d74bdcb.log

ifconfig.txt

@eleanorjboyd

Found the error txt in vscode-1.76.1\src\vs\base\node\macAddress.ts.

If no MAC address is registered then an error is thrown.

[eleanorjboyd]

@sbatten, do you have any thoughts? This specific code that throws the MAC address error has not been edited recently but you seem to be the last person to have touched that code. Looks to be something related in the most recent release is causing this code to error

[sbatten]

I think this is fixed now with microsoft/vscode#176512

[eleanorjboyd]

This change should therefore be out on insiders. I will close this in favor of the other discussion so please post in that issue if you are still seeing problems on insiders or have further questions.
