Error connecting with TLS

[binaryduke]

I'm trying to connect to a 3rd party server that's using OpenSSL.

I've built ixwebsockets on Windows in Visual Studio using vcpkg specifying features : ssl (I've also tried adding and building with ssl and mbedtls as well as ssl and openssl).

The connection is rejected with "error in handshake : SSL - The connection indicated an EOF"

Somewhat stuck. Any tips?

Ive never used this lib before, but if u get an eof at this time and if u activated ssl for ur client, are u sure ur ssl key is correct ?

Can you try to build the ws cli (see top level CMakeLists.txt), and connect to this wss website ?
on macOS it works fine.

or just use the main.cpp example in the README and switch the remote endpoint.

IXWebSocket$ ./build/ws/ws connect wss://echo.websocket.org
Type Ctrl-D to exit prompt...
Connecting to url: wss://echo.websocket.org
