Access via nginx reverse proxy, 404 not found page shows randomly

[CXZ7720]

• code-server version: via dockerhub latest tag
• OS Version: Ubuntu Server 18.04.2 LTS

Description

I pulled code-server via docker command in readme.md
docker run -it -p 127.0.0.1:8443:8443 -v "${PWD}:/home/coder/project" codercom/code-server --allow-http --no-auth with environment option VIRTUAL_HOST=code.example.net for nginx reverse proxy.

When I access the code page, It opens well at first time. But in case of refresh the page or open new tab both default mode and incognito mode via chrome browser, it serves 404 Not found pages.

In container logs,
Error: ENOENT: no such file or directory, open '/src/packages/server/build/web/index.html'

How can I fix it?

Does your nginx config include headers to allow for websocket upgrade requests? Something like the following:

location / {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";

    proxy_pass http://code:8443/;
}

What browser and device are you using to access code-server? We gzip files inside of the code-server binary to make it smaller, so accessing on browsers that don't have gzip support will fail.

If you're using an iPad, try the iPad OS beta.

Hi, I'm attempting to run this on Google Cloud Shell - ideal for this type of environment.

• The system requires you to access through an NGINX reverse proxy.
• The proxy is Google-managed, so I have no way to modify the config. I have the same errors.

Here's the terminal output I've gotten when trying to run the container:

docker run -it -p 0.0.0.0:8443:8443 -v "${PWD}:/home/cameronbrownjames/decoupagedreams.co.uk" codercom/code-server --allow-http --no-auth

Any advice on what I can do? I've attempted setting my VIRTUAL_HOST environment variable which made no difference.

What browser are you using? I doubt that google's proxy will strip Accept-Encoding headers.

@naomi-nori I'll check about it soon. Thanks.
@deansheather I'm using Chrome/73.0.3683.103 and Windows10 1903 x64.

No resolution on this?

We already have some fixes in more recent issues so closing this off.
