Dougie probably did not read the whole thread again and didn't realize that the page is hosted on external server.
He is correct that your format was slightly wrong. You should have "http://" in front and the portnumber needs to be preceded with ":", but "raspberrypi.local" only work on your LAN.
Code: Select all
If you goggle "what is my ip" from any conputer inside your LAN you should get the ip-adress to replace "220.127.116.11".
But the final little hurdle is that you probably can not test this from inside the LAN, using your external IP-address from inside confuses most home routers.
So to verify that the portforwarding is working you can check from the webpage http://canyouseeme.org/
But to test the hosted page properly you have to use a browser on a phone not connected to your wifi but via GSM network or from work or from a friends house.
