Prebuilt version fails on tls handshake

[Rubensei]

I'm trying to connect to a custom host from Node.js but i always get unavailable state

Pusher : : ["State changed","initialized -> connecting"]
Pusher : : ["Connecting",{"transport":"ws","url":"wss://my-domain.com:443/app/MY_APP_KEY?protocol=7&client=js&version=7.0.3&flash=false"}]
Pusher : : ["State changed","connecting -> unavailable"]

I found out that the client automatically closes the TCP session as soon as the TLS handshake finishes
No error is thrown on client and there are no logs at all on the server,
Here the wireshark capture of the tcp handshake and immediate disconnection (the ip ending in 40 corresponds to my device, being the leftmost column the destination address of the packet)

I've been able to connect to the same ws endpoint with the same uri using pusher-client and ws npm packages.

The code i'm using right now:

let pusher = new Pusher(APP_KEY, {
	wsHost: WS_ENDPOINT,
	forceTLS: true,
	enableStats: false,
	enabledTransports: ['ws'],
})

Using
Client

• Pusher-js 7.0.3
• Nodejs 14.15.5
• Windows 10 19042.844

Server

• Nginx with reverse proxy for ws endpoint
• laravel-websockets

Seems to be some issue with certificate validation similar to this. Other clients can still connect fine though

EDIT: Although this allows to connect it doesn't seem to be the issue at all

[Rubensei]

I've been doing some more tests and i've found out that building locally and using that build allows to connect without any error

• Cd to pusher-js folder inside node_modules and download the dependencies with yarn install
• make build_all to build the new files

I believe the issue here is related to the setup on your websocket host.
Does the pre-built library connect ok to official Pusher clusters?

[Rubensei]

Yes, it does connect to the official clusters.

The weird thing is that I tested other ws clients like ws, pusher-client and faye-websocket and all can connect without any issue to the same endpoint using the pre-built lib. While pusher-js can't connect unless I use a locally built version (without any modification at all) as commented before.

Better create a ticket on Pusher support, linking this issue there. Otherwise they won't look into issues.

[benw-pusher]

Thanks for reporting this. We supply our client libraries for connecting to the official Pusher service and do not guarantee support for custom websocket hosts. We are not able to provide a resolution to this issue for this reason.
