[Bug]: Error: WebSocket close with status code 1006 about code-server

[code-asher]

Looks like /config/nginx/proxy.conf contains these lines:

proxy_set_header Host $host;
proxy_set_header X-Forwarded-Host $host;

I think you already tried setting Host, right? code-server will prefer X-Forwarded-Host over Host so it might work to override it:

proxy_set_header X-Forwarded-Host $http_host;

We really need to fix #6166

Oh , yes ! I am setting proxy_set_header X-Forwarded-Host $http_host ，it woks . The port 9091 can connect to the code-server .
Thank you !

Thank you for the reproduction details! I had trouble using them because it seems Swag is trying to generate real certificates and it does not look like they have an option to generate self-signed certificates?

Could you run code-server again with the LOG_LEVEL=debug environment variable and tell me if you see any messages like "blocking request"?
