Can connect to Raspberry Pi using its local IP but not my home IP address

I have port forwarded my Raspberry Pi using the start and end ports as 80 (as I am making an apache web server). I can connect using the local IP address of the Raspberry Pi, but when I attempt to connect using my home IP address (from ipchicken) and port 80 - along with the username and password of the Pi, I either get the error '405 Method not allowed' with WebDav or 'Server unexpectedly closed network connection' with SCP. I have SSH enabled on the Pi. I apologize in advance as I am very new to this stuff - I am just experimenting with my Pi.

If you select port 80 in WinSCP, it automatically switches to WebDAV protocol.
Make sure you select SFTP protocol afterwards.

Hi I tried this and it said 'server unexpectedly closed network connection'.

Can you connect with any other SSH or SFTP client?

No, I cannot.

Then you better ask on some site oriented to Raspberry Pi. Like https://raspberrypi.stackexchange.com/
