VSCode tunnel 1.98.2 fails: legacy server 404 Error

[sdhutchins]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.98.2
• OS Version: CentOS 7

Steps to Reproduce:

The documentation to do that is here: https://docs.rc.uab.edu/cheaha/open_ondemand/hpc_desktop/#downloading-and-installing-vscode-and-vscode-server

Expected Behavior

The CLI should fetch server-linux-x64, not server-linux-legacy-x64, or at least fall back gracefully when the legacy variant is unavailable.

Actual Behavior

The CLI attempts to install a deprecated server-linux-legacy-x64 variant that is no longer hosted by Microsoft, resulting in repeated 404 Not Found errors and failure to connect.

Why I'm Using This Version / Setup

Cheaha runs on CentOS 7, which is officially supported only through VS Code 1.98.2. UAB’s Research Computing documentation explicitly recommends this version as the latest that works with CentOS 7. Due to glibc limitations, later versions of VS Code are not compatible. Remote access using code tunnel is the recommended method per institutional guidance.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.100.2. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

The fix was to revert my local version. I was using the latest local version.
