cWS issue with SSL

[zubairfazal]

Hi

I run a game, before I used to use uWS, but wanted to upgrade to the latest node version so switched to cWS, I had no issues, however when I turned SSL on in my gameserver, I started getting issues, whereas in the old uws I had no issues.

I got some SSL Protocol Error
https://prnt.sc/pkzsqv

Doesnt happen all the time, but sometimes players were unable to connect to my game cos of the error, and would have to either refresh many times to be able to play, or wait for the server to keep retrying connection until player connected.

Because of this issues, I am not able to use SSL within cWS, instead I have had to use an nginx reverse proxy (which works fine)

Im just curious if there is a fix for the SSL inside cWS. This issue never happened to me on the old uws

Sorry by old uws I meant

"uws": "10.148.1"

@zubairfazal yes ssl has some problems in cWS and few latest node versions (however it works correctly in the node versions which are supported by old uws). I dont think that SSL issue is going to get fixed completely. As a work around at this stage would be to use something like nginx in front with ssl.

Oh so your saying if I use cWS with node 8.1.4 it will work fine? (Its what I used for uws)

@zubairfazal After some thoughts from release 0.17 SSL Support has been removed for Node.js 10+ you can use proxy like nginx to set up secure connections. Unfortunately there is no simple way to make it work at the moment i will re review this issue later.

this is not a solution for me :/ because nginx to websocket server is not secure

You could use Traefik in place of nginx.

is it better?

is it better?

It supports websockets and auto Let's encrypt renewal. It's a load balancer and a proxy and handles SSL/TLS. I don't know what do you need exactly. But it's an alternative to nginx, but it's not a webserver.

New version has been released (1.3.0) with SSL support for node 8+. Node 12 and 13 also working except latest 13.9.0 (it has some outstanding issue, use 13.8.x instead). Check out Secure WebSocket section in README as it requires to pass secureProtocol to https to work correctly.

This looks very promising. I will test it this week

@zubairfazal let me know how it goes :)

New release 1.3.1 removes secureProtocol from required option. Now creating wss server is pretty much the same as everywhere else. Only outstanding issue is Node 13.9, looks like internal node js problem, hopefully on next release 13.x it will be fixed till that use 13.8.x :)

I updated to the 1.3.1 version. Was there some API changes from previous versions?

Suddenly my application got this error
