Issue description:

Intended to run code-server behind a subpath/relative path of the host domain like example.com/code, however when visiting that url, browser got redirected to example.com/login?to=%2F instead of example.com/code/login?to=%2F.

In reality, Nginx can be set thus /login?to=%2F is also mapped to code-server, which however defeats the purpose of setting a subpath in terms of the separation of services.

Nginx config:

server {
    listen 80;
    listen [::]:80;
    server_name <example.com>;

    location /code {
      proxy_pass http://localhost:8080/;
      proxy_set_header Host $host;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection upgrade;
      proxy_set_header Accept-Encoding gzip;
    }
}

code-server config.yaml

bind-addr: 127.0.0.1:8080
auth: password
password:<some password>
cert: false

Failed attempts

Tried to set base-url in config.yaml however that option seems to have been removed ever since earlier releases and would result in an error when restarting code-server.

Any suggestion would be appreciated and thanks so much for your time.

I think this is because there's no trailing slash on /code. code-server tries to redirect to a relative path (./login) which with /code ends up being /login.

One solution would be to use nginx to redirect /code to /code/ and then proxy the latter to code-server.

Gotcha, changing to /code/ in Nginx config indeed solves the problem. Thanks a lot!
