websocket_example.c WSS

Postby srlevitt » Tue Sep 14, 2021 5:07 pm

The websocket_example.c fails on esp32 when we try to connect to a secure WSS socket.
I have enabled the default certificate bundle in sdkconfig, and set transport to SSL in the config, but still no luck.
How to get the websocket client to use the certificate bundle?

The debug trace is below:
