Unity 6000.0.45f1 seems broken ( upgrading from Unity 2022 ) - Mono.Security.Interface.TlsException: Failed to create UnityTls context - error code: UNITYTLS_INVALID_ARGUMENT

Hello,

After upgrading from Unity 2022 to latest Unity 6, I am getting:

Pusher Errored with PusherClient.WebsocketException: WebSocket error emitted:

I've tried both 2.1.0+211120 and 2.3.0-beta+230104.

  _pusher = new Pusher(APP_KEY, new PusherOptions()
            {
                Cluster = APP_CLUSTER,
                Encrypted = true,
            });

Changing Encrypted to false makes the client connect successfully.

Not sure if a newer version of WebSocket4Net would work?

We are having the same issues, tried with many versions and by frankeinsteining together come packages but we weren't able to fix it. Did you find a fix for it?

[LucaSilva-r]

After some testing we found out the problem occurs after unity 6000.37f1, so i guess we can use that for now
