Hi :)

It seems the board is locked and there is no way to connect to the board! Is there any way to perform "debug authentication" or discard this by disabling?

Hi everyone!

I was having endless issues like these, and as a last shot I decided to give this video a try. 
STM32 by LowLevel on Youtube 
Going through the steps, and some slight troubleshooting courtesy of ChatGPT made me finally able to connect and upload blink led code!

Hope this helps someone else.

Hi i'm facing similar issue, i believe the issue started when i'm trying to erase flash memory. 
I've tried several things according to this forum but it is not working :
1. Press Reset button while connecting to STM32CubeProgramer
2. Connecting Boot0 and VDD and try to connect

3. Using discovery on debug authentication
