The http IP URL address that became visible in the serial monitor on the line “Camera Ready! Use http address to connect!” I entered on an empty web browser. I get a white page in the browser. I had a Windows Network check performed with result: Your computer seems to be configured correctly but the device or source (URL address) is not responding.
Tried the same thing on another PC. Same problem. However, after about 5 minutes I suddenly got the camera screen. But no image. Only a small white cross appeared in a red circle. Nothing else happened after pressing the Still button.
Feeding with an external supply instead of via the USB cable on the PC did not help.
After logging in to my WIFI modem, the camera URL address was visible, so the camera is connected to the WIFI network. But apparently not approachable.
Being registered with the esp32 cam at the modem was not enough. It turned out that there was not enough WIFI power. So adding an antenna to the module will have to become the solution.
This issue may closed.
