Hello

I tried this testcode :

test wss: 
Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private ws As WebSocketClient
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.Show
    Dim PagesManager As B4XPagesManager
    PagesManager.Initialize(MainForm)
    ws.Initialize("ws")
    'accept all trust manager
    Dim ssl As JavaObject
    ssl.InitializeNewInstance("org.eclipse.jetty.util.ssl.SslContextFactory", Array(True))
    Dim jo As JavaObject = ws
    Dim wsc As JavaObject
    wsc.InitializeNewInstance("org.eclipse.jetty.websocket.client.WebSocketClient", Array(ssl))
    jo.SetField("wsc", wsc)
  
    ws.Connect("wss://b4x.com:51041/smiley/ws")
    'ws.Connect("wss://192.168.4.139:17481")
    Wait For ws_Connected
    Log("connected")
End Sub

'Template version: B4J-1.0

I'm not sure if this is the issue but....
Make sure you're using the latest version of jWebsocketClient:

jWebSocketClientV2

I wish for a jWebSocketClient library (that can have a different name, so as to keep the jWebSocketClient library that's based on Jetty3) that is based on the latest Jetty revision that is included in the latest B4J. This may resolve the Web Socket connect issues found on this forum when it...
www.b4x.com www.b4x.com

And then update your accept all trust manager code to:

jWebSocketClient v2 accept all certificates

Useful when you want to make a not so secure connection to a server with self signed certificate: Sub Process_Globals Private MainForm As Form Private xui As XUI Private ws As WebSocketClient End Sub Sub AppStart (Form1 As Form, Args() As String) MainForm = Form1...
