Please follow the solution below to proceed:

Navigate to the galaxy-rvr-main\galaxy-rvr directory and open the galaxy-rvr.ino file.

Change the line #define SSID “GalaxyRVR” to #define SSID “GalaxyRVR1”. Then, upload the modified galaxy-rvr.ino code again. On your phone, search for and try to connect to the WiFi named “GalaxyRVR” to see if the connection can be established successfully (as shown in the figure).

After successfully connecting to the GalaxyRVR WiFi, proceed to update the ESP32 CAM firmware to version 1.4.2. Then, try connecting to the APP again to see if it works normally.
