I've had a similar problem when I updated to ms-vscode.cpptools-1.3.0-insiders4 this morning.
Had the following showing up in my terminal:
Connection to server got closed. Server will not be restarted.

Log file is not helping much:

[Error - 11:41:28 AM] Connection to server got closed. Server will not be restarted.

I reverted to ms-vscode.cpptools-1.3.0-insiders3 and it works well.

OS and Version: Ubuntu 18.04 (Through Remote.SSH)
VS Code Version: 1.56.0-insider running on Windows

We have not been able to find a repro for this crash yet. Can someone attach a debugger to the cpptools process to get a call stack? (See https://github.com/microsoft/vscode-cpptools/wiki/Attaching-debugger-to-cpptools-or-cpptools%E2%80%90srv).

[sean-mcmanus]

Hmm...but if cpptools is crashing on startup then it might not be possible to attach. Is someone able to get a crash dump via enabling a core dump writer?

[tonyh326]

This crashes every time for me, I can get you any information if you tell me what you need and how to get it.

This was working fine until this morning, when it installed an update.

Version 1.3.0-insiders4: April 6, 2021

[sean-mcmanus]

Does it crash when you open a new folder with just a blank test.cpp in it? Do you have any special C_Cpp settings set?

@tonyh326 What distro/version of Linux are you running on the remote side?
