Hello ledinhphuong,
do you have the problem "Trust anchor for certification path not found" at wss.
Could you tell me, with which wss server did you test you wss connection?
thank you!

I have traditionally tested with http://www.websocket.org/echo.html. You probably have not installed the root certificates on your server. A common problem is only installing your certificate. Check that your SSL server is working correctly using an SSL testing client https://ssltools.thawte.com/checker/views/certCheck.jsp

Thank @damonsu, @palmerc for yours quick response. I don't think this issue belong server side. Steps to reproduce it as below:
1: Configure wifi with http proxy on android device (This feature just comes with android 4.0 or later).

2: Run Debug your Echo app on this device and it goes to exception after tapped Connect button (mTLSEnabled=false, WS_ECHO_SERVER = "ws://echo.websocket.org")

P/s: Websocket works well in chrome app

Does the client work without the Proxy?

[ledinhphuong]

@palmerc Yes, it works well without the proxy.

@palmerc thanks for you answer. I have tried to install a self-signed certificate on my server.
But i get also the same error. Does this library support self-signed certificate?

I have no idea, I've never tried it.
