PDF viewer tries to get files from 127.0.0.1 when running on OpenVSCode

[ryland-goldman]

Environment

• Operating System: Ubuntu 24.04 LTS
• Visual Studio Code Version: OpenVSCode Server v1.91.1 running in Docker v27.1.1
• LaTeX Workshop Version: v10.1.0
• TeX Distribution Version: TeX Live 2024
• I am accessing OpenVSCode Server through a reverse proxy and on Safari v17.5 with macOS 14.5.

The Issue

When I try to access the LaTeX Workshop PDF viewer, it does not load. Given that the log says Internal PDF viewer at http://127.0.0.1:41115, I have think it is trying to load the pdf from 127.0.0.1, which is a different device than the one running VS Code (which is on a server). So it doesn't work because it's trying to load a file that doesn't exist. Other PDF viewer extensions work.

Reproduction Steps

1. Install OpenVSCode Server
2. Install LaTeX Workshop on that server
3. Try to open a PDF

Expected Behavior

Instead of a blank tab, I was expecting to see the PDF rendered.

The extension does not support other vscode versions than the official Microsoft one.
