I was having the same issue as OP with websockets, now I have this in console at ACP.

Using apache, ssl, one instance of nodebb.

same with @priapo, didn't fixed for me.

v6 long polling doesn't work anymore · Issue #2554 · NodeBB/NodeBB

Used version: f403a29 Version which still works: da4014e The long polling just don't work anymore. NodeBB is now trying the whole time to connect to the websockets and just don't try to fallback to longpolling. From Chrome Console: (195)...

Just a thought... what happens when you run npm ls socket.io socket.io-client?

For me:

As mentoined in the issue, the polling and so the transfer works but throws errors if you're idling and no data is transferred while the long polling request.

Are you also up to date with vanilla and lavender? This could be caused by the loading of an old library (v0.9.x) instead of the newest (v1.0.0).

@priapo I can't access your NodeBB right now to check.

priapo

I reinstalled both.. still getting the error... maybe is something with Apache proxy as @raistlinthewiz said he is also using it.

@priapo Caching layer in front of the web server? (varnish etc)

Possibly browser cache?

priapo

No nothing.. I tried installing nginx and used it with the first setup in here, no ssl: https://docs.nodebb.org/en/latest/configuring/proxies/nginx.html still the same. I created another chrome user because of the 301 redirects to https so no cache. Websockets dont work (loading icon stays) and polling throws errors, but at least works...

my config is

{
    "url": "https://bbs.kassius.org",
    "port": "4454",
    "secret": "xxsecret",
    "bind_address": "127.0.0.1",
    "database": "redis",
    "redis": {
        "host": "127.0.0.1",
        "port": "4562",
        "password": "verylongredispass",
        "database": "0"
    },
    "bcrypt_rounds": 12,
    "upload_path": "/public/uploads",
    "use_port": false,
    "socket.io": {
        "transports": ["polling","websocket"]
    }
}

Now it is working for me, it was really something with the proxy on Apache 2.4 and socket.io1.0, I saw this topic:

https://serverfault.com/questions/616370/configuring-apache-2-4-mod-proxy-wstunnel-for-socket-io-1-0`

And configured Apache like this:

Now is working even with pure websockets like "transports": ["websocket"].
It uses Apache's mod_rewrite module.

@priapo ~~Keep in mind putting a socket.io section in config.json doesn't do anything~~

Edit: I stand corrected

priapo

The setting in config.json doesn't affect nodebb? I think it does, see I changed config.json between "transports": ["websocket","polling"] and "transports": ["polling","websocket"] and saw by Chrome Inspector that with websocket as prefered method it doesn't uses polling.

Using "transports": ["polling","websocket"]:

polling

Using "transports": ["websocket","polling"]:

websocket

I see this https://github.com/NodeBB/NodeBB/commit/e0edb71a8ab2f23eaebf5c7557d5d1d19bb55baa

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:
