Difficulties enabling chat extensions (CodeGPT, Continue)

[jokob-sk]

Hi,

Trying to install an extension which I could use to connect to my local Ollama server, however, so far no luck. All the chat interfaces are blank:

I've tried:

1. Installing the extension via the marketplace
2. Installing the extension(s) manually by downloading the VSIX https://www.vsixhub.com/vsix/126451/
3. Rebuilding the container 3x and trying different hosts

Docker-compose seems pretty basic:

services:
  vs-code:
    image: codercom/code-server:latest
    container_name: vs-code
    environment:
      - DEFAULT_WORKSPACE=/mnt/temp  #optional
    volumes:
      - ${APP_DATA_LOCATION}/vs_code/home/coder:/home/coder/
      - ${DIR_CODE}:/mnt/code 
    ports:
      - 4849:8080
    restart: unless-stopped

Any help would be appreciated 🙏

EDIT 1 More details:

If I install the continue extension via the marketplace or via code-server --install-extension continue.continue --force I get the following error:

 ENOENT: no such file or directory, chmod '/home/coder/.continue/server/exe/run'

If I install it manually by downloading VSIX it seems to crash silently (or at least I dont see anything obvious)

Chat extensions (Continue, CodeGPT) show blank panels in code-server because they use VS Code's Extension Host webview APIs with content security policies that differ from the desktop app.

Fix 1: Check browser DevTools console (do this first)

Open browser DevTools (F12) on the code-server tab. Extension webview errors appear there, not in server logs. Look for:

• CSP violations
• Failed to fetch errors
• WebSocket connection failures

Fix 2: Proxy headers for WebSocket support

If behind nginx/Caddy, ensure these headers are set:

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;

Missing Upgrade/Connection headers breaks extension webviews.

Fix 3: Install from Open VSX

code-server uses Open VSX by default. Install the extensions explicitly:

code-server --install-extension Continue.continue
code-server --install-extension danielsanmedium.dscodegpt

Or download .vsix from open-vsx.org and install:

code-server --install-extension /path/to/extension.vsix

Fix 4: Verify Ollama reachability from code-server's perspective

# From the machine running code-server:
curl http://localhost:11434/api/tags

If code-server is in Docker, localhost won't reach the host. Use host.docker.internal (Docker Desktop) or the host's bridge IP instead in your extension settings.
