Struggling to connect WSS with ESP32

[mgk815]

Hello! I am having a similar issue to #101. I have the following board: https://www.adafruit.com/product/5477 and I am trying to connect to a secure web socket: found here https://websocket.org/tools/websocket-echo-server at this endpoint: https://echo.websocket.org/

Here is my code. I tried both the first and second certificate generated by this command (openssl s_client -showcerts -connect websocket.org:443) and neither works. I get the printout "WebSocket Connection Failed! Check server address and SSL certificate." The formatting is not appearing, but it is with the format of

PROGMEM = \

"MIIE6TCCA9GgAwIBAgISAyfetQLKZe+05ueVkHvRbynzMA0GCSqGSIb3DQEBCwUA\n" \

What am I missing?

Thank you!
