ESP32Cam
ESP32Cam Won't OTA! - "No response from ESP"
Platform using Windows 8.1 pro
OTA won't connect - Chrome on port 3232 says refused, pings fine from my nobile on wifi....
Worked fine prior on USB power and working as the camera server... doesn't like OTA
That module is listed in ports
Tried reseting it, now using a dedicated PSU brick to 5V.
Do I need to ground D0?! Thats stupid if so... didn't work, before I moved to brick.
Checked that espota.exe is on private exception in firewall.
only shows HTTPD no 3232
Shit - now only UI shows on http, no streams show

Here is where the error comes from in espota.py:
