First time post. I looked through many posts on this topic but couldn’t figure it out. Thanks in advance for the help.
I am trying to use the video widget to remotely access my ESP32CAM stream (code pasted below). I have successfully done this with the board’s local IP address. In other words, the video widget works locally. But when I use that IP address to get an NGROK link, the widget buffers very briefly and then errors out. The NGROK link checks out on my browser and on my phone when using cellular data. The code pasted below came from a YouTuber who was able to get it working, although the Blynk app he was using looked very different from the current app. Any and all help would be greatly appreciated. Please let me know what further information you would need to help.
Details :
• ESP32 CAM
• iOS 14.8
• Blynk server
• Blynk Library version 1.0.1
/*
This is a simple MJPEG streaming webserver implemented for AI-Thinker ESP32-CAM and
ESP32-EYE modules.
This is tested to work with VLC and Blynk video widget.
