@priapo Keep in mind putting a socket.io section in config.json doesn't do anything 😄
We had just talked about this configuration option short time ago in the issue 😄 so obviously it does affect. But "transports": ["polling","websocket"] is now the Standard.
@priapo if you can't use the websockets you can set also "transports": ["polling"], then you will only get the failures for the long polling request which throws errors.
I just tested by connecting directly without any proxy before NodeBB. The timeout disappears.
So one failure source is that the timeout is higher than what is allowed by the proxy e.g. cloudflare. So an option to adjust the timeout would be great!
The failure throwing which are left now are:
