Hello,

I’ve been running cells for quite a while now and it’s been great. A few days ago I started getting this error on the UI and the Workspaces aren’t syncronizing:  
`Websocket seems to be disconnected: please make sure that the server is up and websocket connection is working`  
I’m running Cells 3.0.9 on a v-server from Strato (no docker) as a systemd service with Debian 10.  
I’ve done some research and it seems to be related to a reverse proxy, I’m running it behind nginx version 1.20.0 . I had upgraded to the new version and thought that maybe this was the problem so I downgraded back to 1.20.0 .  
I copied the config from the instructions and this is my nginx cells config file right now:

```auto
server {
    server_name cells.mydomain.com;

    # Allow any size file to be uploaded.
    client_max_body_size 0;
    # To disable buffering
    proxy_buffering off;

    location / {
        # Uncomment this to enable gRPC and thus be able to use cells-sync
        #if ($http_content_type = "application/grpc") {
        # grpc_pass grpcs://cells:8080;
        #}
        proxy_pass https://localhost:8080;
    }

    location /ws/ {
        proxy_pass https://localhost:8080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

    error_log /var/log/nginx/cells-proxy-error.log;
    access_log /var/log/nginx/cells-proxy-access.log;

    listen [::]:443 ssl;
    listen 443 ssl http2;

    # certificate configuration (in this case generated by certbot)
    ssl_certificate /etc/letsencrypt/live/cells.mydomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/cells.mydomain.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

}

server {
        if ($host = cells.mydomain.com) {
            return 301 https://$host$request_uri;
        }

        listen 80;
        listen [::]:80;
        server_name cells.mydomain.com;
        return 404;
    }

```

When I go to the data sources I see “Node undefined not found”

This is what the data source looks like (I’ve checked, the owner of the folder is the pydio user):

The nginx proxy error log doesn’t give any useful info

`cells ps` just prints out a warning that no private IP was detected for binding broker but doesn’t show the services, most of which aren’t running as I can see from the UI.

Does anyone have any ideas?

Thanks,

Ben

I have absolutely no idea if this helps, but at some point in the past I _really_ had some difficulties getting Pydio Cells to ‘attach’ internally to `localhost`, as you’re doing (aye, I use `nginx` as a reverse proxy as well).

Somewhere (where?) I found a warning that `localhost`, for some obscure reason, would _not_ work with Pydio Cells; instead, one should assign a new, separate, _private_ IP address.

You might have a look at your `/etc/network/interfaces` (or possibly any file inside `/etc/systemd/network/`) and add an extra private IP address to your default network device (I’m assuming Ethernet, or some sort of virtual Ethernet), and configure Pydio Cells to use that one instead — and then change the `nginx` configuration, too.

I’m afraid that I can’t post a working configuration for Debian 10; currently, my production Cells is running under Ubuntu, and the guys from Canonical pushed all the network configurations to use **Netplan** instead…

Hey, thanks for the quick response. Unfortunately my provider says that the network is controlled through Hypervisor so it’s not possible to add another LAN IP ☹ Pretty annoying

Hi,  
by the way, this is what the firefox console shows

```auto
Firefox can’t establish a connection to the server at wss://cells.mydomain.info/ws/event. 2 [login line 1 > injectedScript line 1 > eval:1:3604473](https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval)

WebSocket Closed Connection:The connection was closed abnormally, e.g., without sending or receiving a Close control frame (code 1006) [login line 1 > injectedScript line 1 > eval:1:3931532](https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval)

Error: Internal Server Error

Request https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval:1

emit https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval:1

onreadystatechange https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval:1

[login line 1 > injectedScript line 1 > eval:1:42907](https://cells.mydomain.info/login line 1 > injectedScript line 1 > eval)

```

Basically the same error repeats for `wss://cells.mydomain/ws/chat`

I’d love to hear ideas if anyone has any.  
Thanks,

Ben

Just to get Nginx out of the equation I switched to Apache reverse proxy, I get the exact same errors ☹
