Connecting Litewallet app to Litecoin Core node on home PC

I just installed Litewallet and Litecoin Core and I want to use the litecoin core installation as a node for my Litewallet app wallet. I have the port 9333 forwarded and I know my public IP address, but It doesn’t connect.

Just to add this I also want to make my node a public node for others to use if that is possible.
