Hello Joel,
I cover that issue in this Troubleshooting Unit/Guide: https://rntlab.com/esp32-troubleshooting-guide/
Please read this section “4. A fatal error occurred: “Failed to connect to ESP32: Timed out… Connecting…””. It will explain exactly how to solve your problem.
Let me know if you keep having that problem.
