How to connect to xrdp on wsl from Windows Remote Desktop App

Don't use localhost or 127.0.0.1.

You may receive:

"You have been disconnected because another connection was made to the remote PC" when use localhost.

You may get:

code: 0x4  Extended error code: 0x0 when use 127.0.0.1.

Find your internal ip address, such as 172.31.116.85 by running "ip a" in your wsl command line.

Then you can connect by this address without problem.
