Accessing ESP32-CAM from outside internet

I have an ESP32-CAM set up streaming MJPEG so I can stream it on Blynk. I have set up the server to work on port 81 and when I put in 10.0.1.XX:81/mjpeg/1 I get the video from my local network. I am trying to access it from the internet outside my lan network. I have port forwarded my Airport Extreme for 10.0.1.XX with the ESP32-CAM's mac address on port 81 and when I check the port is shows that the port is not blocked and is accessible. I have set up ddns using no-ip.
The problem is How do I access the ESP32-CAM? What address do I put in my web browser on my phone on only wireless data. I have tried http://10.0.1.XX:81/mjpeg/1 I get a Safari could not open the page because the server stopped responding.
What address should I be putting in. Or is there another problem.

You need to use your external IP address. Check your router. The address should be similar or the same to the one shown in your last post under "Karma". This IP address will typically change on a regular basis.

Worked perfectly. Thanks
