[Bug] Websocket connection failure

[prettydiff]

RomM version 3.2.0

Describe the bug The browser is reporting WebSocket connection failures during scanning.

• Firefox: Firefox can’t establish a connection to the server at ws://games.x/ws/socket.io/?EIO=4&transport=websocket.
• Chrome: index.ec7ff87d.js:60 WebSocket connection to 'ws://games.x/ws/socket.io/?EIO=4&transport=websocket' failed:

To Reproduce Steps to reproduce the behavior:

1. Conduct a library scan
2. Open the developer tools of your browser to the console tab

Expected behavior WebSocket does not fail to connect.

User

• OS: Windows 10

Server

• OS: Docker on Open Media Vault (Debian)

Network

• Home network: 192.168.x.x/24

Additional context I cannot tell if my scans run super long without finding new content because my library is massive or because of this defect.

Can you post the container logs? And are you running romm behind a reverse-proxy like caddy or npm?

I am not running it behind any proxy or reverse proxy.

Firefox says this is the failing code, the ternary:

try {
      this.ws = sv &&
      !ov ? n ? new wa(t, n) : new wa(t) : new wa(t, n, i)
    } catch (o) {
      return this.emitReserved('error', o)
    }
