Hello everyone,

I am deploying a code-server instance with Nginx as a reverse proxy. The two are bundled in one docker container. The plan is to serve code-server under /coder/ subpath, and other services under their unique paths. The editor works fine. I can access the interactive terminal, open every panel, and install extensions from the marketplace. It is just that the extensions are not working.

Here are the details: The code-server and nginx reside in the same container. The code-server is launched with code-server --bind-addr 0.0.0.0:3000 --auth none --cert false and listens at port 3000. The nginx daemon listens at port 80. Its configuration
looks like:

location ~ ^/coder/(.*)$ {
 proxy_pass http://127.0.0.1:3000/1ドル;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "Upgrade";
 proxy_read_timeout 300;
 proxy_set_header Host $http_host;
 proxy_set_header X-Real-IP $remote_addr;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
 add_header Strict-Transport-Security "max-age=15552000; includeSubDomains" always;
 client_max_body_size 0;
 }

The docker container is launched with docker run --rm -p 3000:3000 -p 8000:80 coderwithnginx:latest, exposing both port 3000 and port 80. When accessing via http://127.0.0.1:3000, the extensions work. However when accessing via http://127.0.0.1:8000/coder/, only the editor and terminal work. It looks like the extensions are installed but not activated, and I am getting error messages in the dev console.

What could be the possible causes?
