Facing the same issue. The solution by @guitsilva was working for me earlier, but since last couple of days when try that, I get the following tab that asks for a password to open the file image

Same issue with Remote Container (Docker). Strangely, as reported at the VSCode issues mentioned above, the following workaround temporarily solves the issue:

  1. Open a browser preview: “LaTeX-Workshop side panel” -> “Commands” -> “View LaTeX PDF” -> “View in web browser”.

  2. Close the browser preview.

  3. Open a VSCode tab preview: “LaTeX-Workshop side panel” -> “Commands” -> “View LaTeX PDF” -> “View in VSCode tab”.

This workaround is just a palliative and only fix the problem until you restart VSCode.

You can downgrade to VS Code 1.46 with binaries in the release note:

If you want this issue fixed soon, please upvote microsoft/vscode/issues/102449. I doubt this issue will be fixed in the next release, VS Code 1.49.

We can do nothing on our side as far as I tried.

(fyi) VS Code 1.49 was just released, and so far PDF preview has been working fine again (at least for connections into WSL2). There also was some update for the remote extensions related to “Automatically forward ports”, which might actually remedy the issue.

For what it’s worth, if you click on the ‘View LaTeX PDF file’ button (Ctrl + Alt + v) while VSCode is starting the PDF tab loads correctly.

I could fix the bug in 1.47.3 by applying the following config to devcontainer.json:

{
   ...
  "forwardPorts": [ 35556 ],
  "settings": {
     "latex-workshop.viewer.pdf.internal.port": 35556,
    ...
  },
}

I guess the problem occurs due to the default value "0" of the property latex-workshop.viewer.pdf.internal.port. Either because it is randomly chosen, or because it is a string instead of a number?

In 1.48, the behavior got worse. Opening does not work out of the box, still. But when using the browser-work-around, the PDF is not rendered. I just see strange buttons and text 😦

CheariX on Aug 15, 2020

I can reproduce. It seems to be a vscode webview+remote dev bug. Also see https://github.com/Ikuyadeu/vscode-R/issues/380

I am still seeing this issue in v1.49.1 with Remote SSH v0.55.0. Same on today’s insiders 1.50.0 with the same Remote SSH.

For remote ssh it works but only after I set up port forwarding manually or by clicking “View in web browser”.

May I ask how you did that? Did you just enable “port forwarding” somewhere, or did you have to set up specific ports?

Sure, there are two different ways to do the same thing (i.e., set up port forwarding), so choose only one of them:

  1. Manual setup: follow instructions here. The key is to choose the correct port to forward. Usually the one listened by /home/<username>/.vscode-server/bin/.../node is the one to go.
  2. Open preview in browser: follow instructions here. Somehow doing so sets up the port forwarding automatically.

  1. If I close the PDF tab before I exit vscode, then next time I can preview PDF in vscode. Everything works for me.

  2. If I forget close the PDF tab before I exit vscode, next time when I open vscode, the PDF tab will be there but no pdf showing. And I can not preview PDF any more.

Can confirm that the workaround @guitsilva mentioned also works for Remote SSH.
