ESP32 Wifi Secure Client - no connection

Using Arduino Networking, Protocols, and Devices
#1

I am trying to connect the ESP32 to the network. But it keeps failing.
I use the WifiSecureClient library with a CA key.
It always fails with:

[E][esp32-hal-cpu.c:115] removeApbChangeCallback(): not found func=400D749C arg=3FFBEDB0
[D][WiFiGeneric.cpp:332] _eventCallback(): Event: 0 - WIFI_READY
[D][WiFiGeneric.cpp:332] _eventCallback(): Event: 2 - STA_START
.................................................................

What is the problem? The Problem is also on the normal Wifi library.

What is the problem?

The problem is you didn't read the sticky post at the top of the topic. There you would have found that you should post your complete code (using code tags!) to enable use to reproduce what your board is doing.

If you have additional hardware attached, post a wiring diagram!
