You will never reconnect to code-server because the socket file is delete.

Expected

Never delete the socket file unless code-server is stopped

Actual

It deleted!

Are you accessing code-server over a secure context?

• I am using a secure context.

Notes

my nginx config:

server {
    include common/listen-8096;
    server_name my.super.server;
    # set max upload size
    client_max_body_size 32G;
    fastcgi_buffers 64 4K;

  
    location / {
        proxy_pass http://unix:/dev/shm/code-server.sock;
        
        add_header Access-Control-Allow-Origin *;
         add_header Access-Control-Allow-Methods *;
         add_header Access-Control-Allow-Headers *;
 
         # proxy_ssl_verify off;
         proxy_set_header Host $host;
         proxy_set_header Accept-Encoding gzip;
         #proxy_set_header X-Forwarded-Host $host;
         proxy_set_header X-Forwarded-Host $host:$server_port;
 
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection $http_connection;
         proxy_http_version 1.1;

        access_log /var/log/nginx/code.log;
        error_log /var/log/nginx/code.error.log;
    }  
}

And systemctl edit code-server.service:

Are you sure the socket is deleted? That socket should be unrelated to the web socket in the console messages (the three hour one).

The timeout is one specified by VS Code, not us, but we could patch it if we really need to. From what I understand, it is really just meant to reconnect when there is a blip in the network. Reloading the page should result in a new connection, but is that not working either?

@code-asher Thanks for your reply and I’m pretty sure the socket file is gone

[code-asher]

Yikes, that definitely seems like a bug.

[code-asher]

Supposedly, the only time we delete the socket is when code-server is first started. Is it possible a second instance of code-server was ran that deleted the socket?

Although, not sure that makes sense because then we should still see the socket from the second instance. I do not see that we delete the socket anywhere else though.

[Mars160]

I don't know if it's possible. I just installed code-server via aur and ran it with systemctl. I personally prefer that it's unlikely.

And I checked all my crontab script to ensure there is no script which will delete the socket file

It's so weird.

Maybe I should write a script to keep checking it the socket file is there and try to find the precise time the socket file is deleted

[code-asher]

That is definitely strange. If you are able to debug more that would be awesome. I can try running with a socket next week and see if I can reproduce.
