@ESP32 TEAM Could you help me resolve this issue

Hi parthu 123,

I have encountered similar problems in my project. What I can't explain is that, at the beginning, everything worked well. After a while, however, the OCD server could no longer connect to my ESP32S3. After some testing, I discovered that the name of the debug configuration needed to be without spaces. Once I removed the spaces, it worked seamlessly.

regards,
Benedikt
